DESCRIPTION

The INA159 is a high slew rate, G = 1/5 difference

amplifier consisting of a precision op amp with a

precision resistor network. The gain of 1/5 makes the INA159 useful to couple ±10-V signals to

single-supply analog-to-digital converters (ADCs),

particularly those operating on a single +5-V supply.

The on-chip resistors are laser-trimmed for accurate

gain and high common-mode rejection. Excellent

temperature coefficient of resistance (TCR) tracking

of the resistors maintains gain accuracy and

common-mode rejection over temperature. The input

common-mode voltage range extends beyond the

positive and negative supply rails. It operates on a

total of 1.8-V to 5.5-V single or split supplies. The INA159 reference input uses two resistors for easy

mid-supply or reference biasing.

The difference amplifier is the foundation of many

commonly-used circuits. The INA159 provides this circuit function without using an expensive external

precision resistor network. The INA159 is available in

an MSOP-8 surface-mount package and is specified

for operation over the extended industrial temperature

range, –55°C to 125°C.
