Introduction
The INA2128 is a dual, low power, general purpose instrumentation amplifier offering excellent accuracy. Its versatile 3-op amp design and small size make it ideal for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain (200kHz at G = 100). A single external resistor sets any gain from 1 to 10,000. Internal input protection can withstand up to ±40V without damage. The INA2128 is laser-trimmed for very low offset voltage (50μV), drift (0.5μV/°C) and high common-mode rejection (120dB at G ≥ 100). It operates with power supplies as low as ±2.25V, and quiescent current is only 700μA per IA—ideal for battery-operated and multiple-channel systems. The INA2128 is available in SOL-16 packages, specified for the -40°C to +85°C temperature range.
Features
- LOW OFFSET VOLTAGE: 50μV max
- LOW DRIFT: 0.5μV/°C max
- LOW INPUT BIAS CURRENT: 5nA max
- HIGH CMR: 120dB min
- INPUTS PROTECTED TO ±40V
- WIDE SUPPLY RANGE: ±2.25V to ±18V
- LOW QUIESCENT CURRENT: 700μA / IA
- 16-PIN PLASTIC DIP, SOL-16
Applications
- SENSOR AMPLIFIER (THERMOCOUPLE, RTD, BRIDGE)
- MEDICAL INSTRUMENTATION
- MULTIPLE-CHANNEL SYSTEMS
- BATTERY OPERATED EQUIPMENT
