INA118U TI Instrumentation, OP Amps, Buffer Amps

The INA118U is a precision, low-power instrumentation amplifier from Texas Instruments, featuring a single external resistor gain setting from 1 to 10,000. It operates over a supply range of ±1.35V to ±18V and offers ultra-low input bias current of 1 nA. The device provides a low offset voltage of 50 μV and a high common-mode rejection ratio (CMRR) of 110 dB at G=1000. Housed in an 8-pin SOIC package, it operates over -40°C to 85°C. Applications include medical instrumentation (ECG), industrial process control, bridge amplifiers, and low-level transducer interfaces. In stock at HL Electronics – request a quote for fast delivery.
