The LT
廬
1469 is a dual, precision high speed operational
amplifier with 16-bit accuracy and 900ns settling to 150碌V
for 10V signals. This unique blend of precision and AC
performance makes the LT1469 the optimum choice for
high accuracy applications such as DAC current-to-volt-
age conversion and ADC buffers. The initial accuracy and
drift characteristics of the input offset voltage and invert-
ing input bias current are tailored for inverting applica-
tions.
The 90MHz gain bandwidth ensures high open-loop gain
at frequency for reducing distortion. In noninverting appli-
cations such as an ADC buffer, the low distortion and DC
accuracy allow full 16-bit AC and DC performance.
The 22V/碌s 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 manufactured on Linear Technology鈥檚
complementary bipolar process and is available in 8-pin
PDIP and SO packages. A single version,the LT1468, is
also available.
