INA121 INA121 ® INA121 FET-Input, Low Power INSTRUMENTATION AMPLIFIER FEATURES DESCRIPTION lLOW BIAS CURRENT: ±4pA The INA121 is a FET-input, low power instrumenta- tion amplifier offering excellent accuracy. Its versatile lLOW QUIESCENT CURRENT: ±450μA three-op amp design and very small size make it ideal lLOW INPUT OFFSET VOLTAGE: ±200μV for a variety of general purpose applications. Low bias lLOW INPUT OFFSET DRIFT: ±2μV/°C current (±4pA) allows use with high impedance lLOW INPUT NOISE: sources. 20nV/√Hz at f = 1kHz (G =100) Gain can be set from 1V to 10,000V/V with a single lHIGH CMR: 106dB external resistor. Internal input protection can with- stand up to ±40V without damage.lWIDE SUPPLY RANGE: ±2.25V to ±18V The INA121 is laser-trimmed for very low offsetlLOW NONLINEARITY ERROR: 0.001% max voltage (±200μV), low offset drift (±2μV/°C), and lINPUT PROTECTION TO ±40V high common-mode rejection (106dB at G = 100). It l8-PIN DIP AND SO-8 SURFACE MOUNT operates on power supplies as low as ±2.25V (+4.5V), allowing use in battery operated and single 5V sys- APPLICATIONS tems. Quiescent current is only 450μA. Package options include 8-pin plastic DIP and SO-8lLOW-LEVEL TRANSDUCER AMPLIFIERS surface mount. All are specified for the –40°C to Bridge, RTD, Thermocouple +85°C industrial temperature range. lPHYSIOLOGICAL AMPLIFIERS ECG, EEG, EMG, Respiratory lHIGH IMPEDANCE TRANSDUCERS lCAPACITIVE SENSORS lMULTI-CHANNEL DATA ACQUISITION lPORTABLE, BATTERY OPERATED SYSTEMS lGENERAL PURPOSE INSTRUMENTATION V+ 7 INA121 2 Over-Voltage – V IN Protection A 50kΩ 1 G = 1 + 40kΩ 40kΩ R G 1 25kΩ 6 A V R G 3 O 8 25kΩ 5 A Ref 2 3 Over-Voltage + 40kΩ 40kΩ V IN Protection 4 V– International Airport Industrial Park • Mailing Address: PO Box 11400, Tucson, AZ 85734 • Street Address: 6730 S.
