APPLICATIONS

DESCRIPTION

Dual 200MHz, 30V/µs

tional amplifier 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 filters and

instrumentation amplifiers compared to other precision

op amps.

The LT1469-2 is specified 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.
