PRODUCT DESCRIPTION The SGM8554 is a quad rail-to-rail input and output precision operational amplifier which has low input offset voltage, and bias current. It is guaranteed to operate from 2.5V to 5.5V single supply. The rail-to-rail input and output swings provided by the SGM8554 make both high-side and low-side sensing easy. The combination of characteristics makes the SGM8554 good choices for temperature, position and pressure sensors, medical equipment and strain gauge amplifiers, or any other 2.5V to 5.5V application requiring precision and long term stability. The SGM8554 is specified for the extended industrial/ automotive (-4 to +125 ) temperature range. It is offered in SOIC-14 and TSSOP-14 packages. FEATURES Low Offset Voltage: 12μV (TYP) Rail-to-Rail Input and Output Swing 2.5V to 5.5V Single Supply Operation Voltage Gain: 145dB (TYP) at +5V PSRR: 11dB (TYP) CMRR: 15dB (TYP) Ultra Low Input Bias Current: 1pA Low Supply Current: 465μA/Channel Overload Recovery Time: 6µs (at V S = +5V) No External Capacitors Required -4 to +125 Operating Temperature Range Available in Green SOIC-14 and TSSOP-14 Packages PIN CONFIGURATIONS (TOP VIEW) SGM8554 APPLICATIONS Temperature Measurements Pressure Sensors OUTA -INA 1 2 14 13 OUTD -IND Precision Current Sensing Electronic Scales Strain Gauge Amplifiers +INA +V S 3 12 4 11 +IND -V S Medical Instrumentation Thermocouple Amplifiers Handheld Test Equipment +INB -INB 5 6 1 9 +INC -INC OUTB 7 8 OUTC SOIC-14/TSSOP-14 REV.

SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. SGMICRO reserves the right to make any change in circuit design, specification or other related things if necessary without notice at any time. Please contact SGMICRO sales office to get the latest datasheet. NOTE: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2
