DESCRIPTION
Dual 200MHz, 30V/s
16-Bit Accurate AV ≥ 2 Op Amp
The LT1469-2 is a dual, precision high speed opera-
tional amplier with 16-bit accuracy, decompensated to
be stable in a gain of 2 or greater. The combination of
precision and AC performance makes the LT1469-2 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 LT1469-2 improves large-signal
performance in applications such as active lters and
instrumentation ampliers compared to other precision
op amps.
The LT1469-2 is specied on power supply voltages of
±5V and ±15V and from –40°C to 85°C. It is available in
an 8-lead SOIC package and a space saving 4mm × 4mm
leadless package. For a unity-gain stable op amp with same
DC performance, see the LT1469 datasheet.
