1 Low cost low power input/output rail-to-rail operational amplifiers Features Operating range from V CC = 2.7V to 6V Rail-to-rail input and output Extended V icm (V DD -.2V to V CC +.2V) Low supply current (145µA) Gain bandwidth product (1MHz) ESD tolerance (2kV) Latch-up immunity Available in SOT23-5 micropackage Non Inverting Input VDD Inverting Input LMV321ILT (SOT23-5) _ LMV321RILT (SOT23-5) 5 4 VCC Output Applications Output 1 5 VCC Two-cell battery-powered systems Battery-powered electronic equipment Cordless phones Personal medical care (glucose meter) Laptops PDAs Description The LMV321/358/324 family (single, dual and quad) answer the need for low cost, general purpose operational amplifiers. It operates with voltages as low as 2.7V and features both input and output rail-to-rail, 145µA consumption current and 1MHz gain bandwidth product (GBP). With a such low consumption and a sufficient GBP for many applications, these op-amps are very well-suited for any kind of battery-supplied and portable equipment application. The LMV321 is housed in the space-saving 5-pin SOT23-5 package which simplifies the board design (outside dimensions are 2.8mm x 2.9mm). The SOT23-5 has two pinning configurations to answer all application requirements.

All voltage values, except differential voltage are with respect to network terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. If V id > ±1V, the maximum input current must not exceed ±1mA. In this case (V id > ±1V), an input series resistor must be added to limit input current. 3. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous shortcircuits on all amplifiers. All values are typical C/W 81 4 C/W kv HBM: human body model (4) MM: machine model (5) 2 V CDM: charged device model (6) 1.5 kv Lead temperature (soldering, 1sec) 25 C Output short-circuit duration see note (7) 4. Human body model: A pf capacitor is charged to the specified voltage, then discharged through a 1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 5. Machine model: A 2pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5Ω). This is done for all couples of connected pin combinations while the other pins are floating. 6. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. No value specified for CDM on SOT23-5L package. The value is given for SO and TSSOP packages. 7. Short-circuits from the output to V CC can cause excessive heating. The maximum output current is approximately 48mA, independent of the magnitude of V CC. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. 2/15
