90MHz, 22V/µs
16-Bit Accurate
Operational Amplifier
DESCRIPTION
The LT
®
1468 is a precision high speed operational amplifier
with 16-bit accuracy and 900ns settling to 150μV for 10V
signals. This unique blend of precision and AC performance
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 character-
istics 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 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 a complementary bipolar
process. It is available in a space saving 3mm
×
3mm lead-
less package, as well as small outline and DIP packages.
