DESCRIPTIO
U
The LT
1468 is a precision high speed operational ampli-
fier with 16-bit accuracy and 900ns settling to 150
μ
V for
10V signals. This unique blend of precision and AC perfor-
mance makes the LT1468 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 appli-
cations such as an ADC buffer, the low distortion and DC
accuracy allow full 16-bit AC and DC performance.
The 22V/
μ
s slew rate of the LT1468 improves large-signal
performance in applications such as active filters and
instrumentation amplifiers compared to other precision
op amps.
The LT1468 is manufactured on Linear Technology’s
complementary bipolar process.
