LT1215/LT1216

23MHz, 50V/µs, Single Supply

Dual and Quad

Precision Op Amps

DESCRIPTIO

FEATURES

Slew Rate: 50V/µs Typ

TheLT^®1215isadual,singlesupplyprecisionopampwith

a 23MHz gain-bandwidth product and a 50V/µs slew rate.

The LT1216 is a quad version of the same amplifier. The

DC precision of the LT1215/LT1216 eliminates trims in

most systems while providing high frequency perfor-

mance not usually found in single supply amplifiers.

■

Gain-Bandwidth Product: 23MHz Typ

■

Fast Settling to 0.01%

2V Step to 200µV: 250ns Typ

10V Step to 1mV: 480ns Typ

■

Excellent DC Precision in All Packages

Input Offset Voltage: 450µV Max

Input Offset Voltage Drift: 10µV/°C Max

Input Offset Current: 120nA Max

Input Bias Current: 600nA Max

Open-Loop Gain: 1000V/mV Min

The LT1215/LT1216 will operate on any supply greater

than 2.5V and less than 36V total. These amplifiers are

specified on single 3.3V, single 5V and ±15V supplies, and

only require 5mA of quiescent supply current per ampli-

fier. The inputs can be driven beyond the supplies without

damage or phase reversal of the output. The minimum
