INA129U General Description
The INA128 and INA129 (INA12x) are low-power, general-purpose instrumentation amplifiers that offer excellent accuracy. The versatile three op amp design and small size make these amplifiers an excellent choice for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain (200 kHz at G = 100).
A single external resistor sets any gain from 1 to 10,000. The INA128 provides an industry-standard gain equation with a 50-kΩ resistor. The INA129 gain equation uses a 49.4-kΩ resistor to allow for drop-in replacements of comparable devices.
The INA12x are available in plastic DIP and surface-mount packages, specified for the –40°C to +85°C temperature range. The INA128 is also available in a dual configuration, the INA2128.
The upgraded INA828 offers a lower input bias current (0.6 nA, max) and lower noise (7 nV/√Hz) at the same quiescent current. See the Device Comparison Table for a selection of precision instrumentation amplifiers from Texas Instruments.
Features
- Low offset voltage: 50 µV, maximum
- Low drift: 0.5 µV/°C, maximum
- Low input bias current: 5 nA, maximum
- Low noise: 8 nV/√Hz, 0.2 µVpp
- High CMR: 120 dB, minimum
- Bandwidth: 1.3 MHz (G = 1)
- Inputs protected to ±40 V
- Wide supply range: ±2.25 V to ±18 V
- Low quiescent current: 700 µA
- Packages: 8-pin plastic DIP, SO-8
