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.
