DESCRIPTION
Dual 90MHz, 22V/s
16-Bit Accurate Operational Amplifier
The LT1469 is a dual, precision high speed operational
amplifier with 16-bit accuracy and 900ns settling to 150V
for 10V steps. This unique blend of precision and AC
performance makes the LT1469 the optimum choice for
highaccuracyapplicationssuchasDACcurrent-to-voltage
conversion and ADC buffers. The initial accuracy and drift
characteristicsoftheinputoffsetvoltageandinvertinginput
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/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 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.
