DESCRIPTION

200MHz, 30V/µs

16-Bit Accurate

fier with 16-bit accuracy, decompensated to be stable in a

gain of 2 or greater. The combination of precision and AC

performance makes the LT1468-2 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 200MHz 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 high slew rate of the LT1468-2 improves large-signal

performance in applications such as active filters and

instrumentation amplifiers compared to other precision

op amps.

The LT1468-2 is specified on power supply voltages of

±5V and ±15V and from –40°C to 85°C. For a unity-gain

stable op amp with same DC performance, see the LT1468

datasheet.
