TPA1286

High Voltage, Precision, Zero-drift, Instrumentation Amplifier

◼

Precision current measurement

Features

Description

◼

Excellent DC specifications

◆

Small voltage offset: ±50uV (MAX)

The TPA1286 is a low cost, wide supply range instrumentation

amplifier that requires only one external resistor to set any gain

between 1 and 1,000. The TPA1286 is designed to work with

a variety of single voltages. A wide input range and rail-to-rail

output allow the signal to make full use of the supply rails. Low

voltage offset, low offset drift, low gain drift, high gain

accuracy, and high CMRR make this part an excellent choice

in applications that demand the best DC performance.

The TPA1286 operates from single 4V to 36V supply, offers

breakthrough performance throughout the −40°C to +125°C

temperature range. It features a zero-drift core, which leads to

a typical offset drift of 0.2μV/°C throughout the operating

temperature range.

Small voltage offset drift: 0.2μV/°C (MAX)

Small input bias current: 1.5nA (MAX)

◼

Excellent AC specifications

◆

CMRR: 80dB @ G=1 (MIN)

Small input noise: 15nV/√Hz @ G=10

Input noise (0.1 Hz to 10 Hz): 1 μV p-p

-3dB Bandwidth: 1.6MHz

Slew rate: 5V/us

◼

Gain set with 1 external resistor (gain range 1 to 1,000)

SUPPLY VOLTAGE: ±2V to ±18V

RAIL to RAIL for VOLTAGE OUTPUT

Operating Temperature: –45°C to +125°C
