LT1469

Dual 90MHz, 22V/µs

16-Bit Accurate Operational Amplifier

FEATURES

DESCRIPTION

The LT

1469 is a dual, precision high speed operational

amplifier with 16-bit accuracy and 900ns settling to 150µV

for 10V steps. This unique blend of precision and AC

performance makes the LT1469 the optimum choice for

high accuracy applications such as DAC current-to-voltage

conversion and ADC buffers. The initial accuracy and drift

characteristics of the input offset voltage and inverting input

bias current are tailored for inverting applications.

The 90MHz gain bandwidth ensures high open-loop gain

at frequency for reducing distortion. In noninverting ap-

plications such as an ADC buffer, the low distortion and

DC accuracy allow full 16-bit AC and DC performance.

The 22V/µs slew rate of the LT1469 improves large signal

performance compared to other precision op amps in

applications such as active filters and instrumentation

amplifiers.

The LT1469 is available in a space saving 4mm

4mm

leadless package, as well as in small outline and DIP pack-

ages. A single version, the LT1468, is also available.
