LT Precision, Micropower, Single Supply Instrumentation Amplifier (Fixed Gain = or ) DESCIPTIO U The LT establishes the following milestones: () It is the first micropower instrumentation amplifier, () It is the first single supply instrumentation amplifier, () It is the first instrumentation amplifier to feature fixed gains of and/or in low cost, space-saving -lead packages. The LT is completely self-contained: no external gain setting resistor is required. The LT combines its micropower operation (µa supply current) with a gain error of.%, gain linearity of ppm, gain drift of ppm/ C. The output is guaranteed to drive a k load to ±V with excellent gain accuracy. Other precision specifications are also outstanding: µv input offset voltage, pa input offset current, and low drift (.µv/ C and.pa/ C). In addition, unlike other instrumentation amplifiers, there is no output offset voltage contribution to total error. A full set of specifications are provided with ±V dual supplies and for single V supply operation. The LT can be operated from a single lithium cell or two Ni-Cad batteries. Battery voltage can drop as low as.v, yet the LT still maintains its gain accuracy. In single supply applications, both input and output voltages swing to within a few millivolts of ground. The output sinks current while swinging to ground no external, power consuming pull down resistors are needed. TYPICAL APPLICATIO U Gain Error Distribution GOUND (EF) SHOT TO, G = N.C.

Both the input common mode range and the output swing are within a few millivolts of ground. Probably the most common application for instrumentation amplifiers is amplifying a differential signal from a transducer or sensor resistance bridge. All competitive instrumentation amplifiers have a minimum required common mode voltage which is V to V above the negative supply. This means that the voltage across the bridge has to be V to V or dual supplies have to be used (i.e., micropower) single battery usage is not attainable on competitive devices. The minimum output voltage obtainable on the LT is a function of the input common mode voltage. When the common mode voltage is high and the output is low, current will flow from the output of amplifier A into the output of amplifier B. See the Minimum Output Voltage vs Common Mode Voltage plot. Similarly, the Single Supply Minimum Common Mode Voltage vs Output Voltage plot specifies the expected common mode range. When the output is high and input common mode is low, the output of amplifier A has to sink current coming from the output of amplifier B. Since amplifier A is effectively in unity gain, its input is limited by its output. Common Mode ejection vs Frequency The common mode rejection ratio (CM) of the LT starts to roll off at a relatively low frequency. However, as shown on the Common Mode ejection atio vs Frequency plot, CM can be enhanced significantly by connecting an pf capacitor between pins and. This improvement is only available in the gain configuration, and it is in excess of db at Hz. Offset Nulling The LT is not equipped with dedicated offset null terminals. In many bridge transducer or sensor applications, calibrating the bridge simultaneously eliminates the instrumentation amplifier s offset as a source of error. For example, in the Micropower emote Temperature Sensor Application shown, one adjustment removes the offset errors due to the temperature sensor, voltage reference and the LT. fa
LT APPLICATIO S I FO ATIO U W U U A simple resistive offset adjust procedure is shown below. If = Ω for G =, and = Ω for G =, then the effect of on gain error is approximately.%. Unfortunately, about µa has to flow through to bias the reference terminal (Pin ) and to null out the worstcase offset voltage. The total current through the resistor network can exceed ma, and the micropower advantage of the LT is lost. V LT V LT AI Another offset adjust scheme uses the LT micropower op amp to drive the reference Pin. Gain error and common mode rejection are unaffected, the total current increase is µa. The offset of the LT is trimmed and amplified to match and cancel the offset voltage of the LT. Output offset null range is ±mv. LT k k k k POT k.v TO V LT k.k Gains Between and Gains between and can be achieved by connecting two equal resistors (= x ) between Pins and and Pins and. x Gain = x /9 The nominal value of is 9.kΩ. The usefulness of this method is limited by the fact that is not controlled to better than ±% absolute accuracy in production. However, on any specific unit, 9 can be measured between Pins and. Input Protection Instrumentation amplifiers are often used in harsh environments where overload conditions can occur. The LT employs PNP input transistors, consequently the differential input voltage can be ±V (with ±V supplies, ±V with ±V supplies) without an increase in input bias current. Competitive instrumentation amplifiers have NPN inputs which are protected by back-to-back diodes. When the differential input voltage exceeds ±.V on these competitive devices, input current increases to the milliampere level; more than ±V differential voltage can cause permanent damage. When the LT s inputs are pulled above the positive supply, the inputs will clamp a diode voltage above the positive supply. No damage will occur if the input current is limited to ma. Ω resistors in series with the inputs protect the LT when the inputs are pulled as much as V below the negative supply..v TO V LT AI fa
