DESCRIPTION

The INA154 is a high slew rate, unity-gain difference

amplifier consisting of a precision op amp with a

precision resistor network. The on-chip resistors are

laser trimmed for accurate gain and high common-

mode rejection. Excellent TCR tracking of the resis-

tors maintains gain accuracy and common-mode re-

jection over temperature. The input common-mode

voltage range extends beyond the positive and nega-

tive supply rails. It operates on

±4V to ±18V supplies.

The difference amplifier is the foundation of many

commonly used circuits. The INA154 provides this

circuit function without using an expensive precision

resistor network. The INA154 is available in a SO-8

surface-mount package and is specified for operation

over the extended industrial temperature range, –40

°C

to +85

°C.
