The LT
®
1468-2 is a precision high speed operational ampli-
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
data sheet.
