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.
