Precision, Gain of 0.2 Level Translation

DIFFERENCE AMPLIFIER

F_DEATURES

DESCRIPTION

GAIN OF 0.2 TO INTERFACE 10V SIGNALS

TO SINGLE-SUPPLY ADCs

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 10V signals to single-supply analog-to-digital

converters (ADCs), particularly those operating on a single

+5V 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 +1.8V to +5.5V single

or split supplies. The INA159 reference input uses two

resistors for easy mid-supply or reference biasing.

GAIN ACCURACY: 0.024% (max)

WIDE BANDWIDTH: 1.5MHz

HIGH SLEW RATE: 15V/µs

LOW OFFSET VOLTAGE: 100µV

LOW OFFSET DRIFT: 1.5µV/°C

SINGLE-SUPPLY OPERATION DOWN TO 1.8V

INDUSTRIAL PROCESS CONTROLS

INSTRUMENTATION

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, −40°C to

+125°C.
