● G = +10 AMPLIFIER

● G = –10 AMPLIFIER

● G = +11 AMPLIFIER

● INSTRUMENTATION AMPLIFIER

DESCRIPTION

The INA106 is a monolithic Gain = 10 differential amplifier

consisting of a precision op amp and on-chip metal film

resistors. The resistors are laser trimmed for accurate gain

and high common-mode rejection. Excellent TCR tracking

of the resistors maintains gain accuracy and common-mode

rejection over temperature.

The differential amplifier is the foundation of many com-

monly used circuits. The INA106 provides this precision

circuit function without using an expensive resistor network.

The INA106 is available in 8-pin plastic DIP and SO-8

surface-mount packages.

FEATURES

● ACCURATE GAIN: ±0.025% max

● HIGH COMMON-MODE REJECTION: 86dB min

● NONLINEARITY: 0.001% max

● EASY TO USE

● PLASTIC 8-PIN DIP, SO-8 SOIC
