Precision, Zero-Drift, High-Voltage,

Programmable Gain Instrumentation Amplifier

Check for Samples: PGA281

FEATURES

DESCRIPTION

The PGA281 is a high-precision instrumentation

234

•

Wide Input Range: ±15.5 V at ±18 V Supply

Binary Gain Steps: 128 V/V to ⅛ V/V

Additional Scaling Factor: 1 V/V and 1⅜ V/V

Low Offset Voltage: 5 μV at G = 128

Near-Zero Long-Term Drift of Offset Voltage

Near-Zero Gain Drift: 0.5 ppm/°C

Excellent Linearity: 1.5 ppm

Excellent CMRR: 140 dB

amplifier with a digitally-controllable gain and signal-

integrity test capability. This device uses proprietary

autozeroing techniques to offer low offset voltage,

near-zero offset and gain drift, excellent linearity, and

nearly no 1/f noise.

•

The PGA281 is optimized to provide an excellent

common-mode rejection of greater than 110 dB (G =

1) over a wide frequency range. Superior common-

mode and supply rejection supports high-resolution,

precise measurement. The 36-V supply capability and

wide, high-impedance input range comply with

requirements for universal signal measurement.

High Input Impedance

Very Low 1/f Noise

Differential Signal Output

The PGA281 offers multiple internal gain options from

⅛ V/V (attenuation) to 176 V/V, making this a

suitable for a wide variety of applications. The fully

differential, rail-to-rail output is designed to easily

interface a wide range of input signals to the low-

voltage domain of high-resolution analog-to-digital

converters (ADCs).
