LT1492/LT1493

5MHz, 3V/µs, Low Power

Single Supply, Dual and Quad

Precision Op Amps

FEATURES

DESCRIPTION

The LT^®1492/LT1493 are dual/quad, low power, single sup-

ply precision op amps with 5MHz gain-bandwidth product,

3V/µs slew rate and only 450µA of quiescent supply current

per amplifier.

■

Gain-Bandwidth Product: 5MHz Typ

■

Slew Rate: 3V/µs Typ

■

Low Supply Current per Amplifier: 0.55mA Max

■

Input Offset Voltage: 180µV Max

■

Input Offset Voltage Drift: 3µV/°C Max

With a maximum input offset voltage of only 180µV, the

LT1492/LT1493 eliminate trims in most systems while pro-

viding high frequency performance not usually found in low

power single supply amplifiers.

■

Input Offset Current: 20nA Max

■

Input Bias Current: 100nA Max

■

Open-Loop Gain: 1500V/mV Min (V_S= ±15V)

■

Low Input Noise Voltage: 16.5nV/√Hz

The LT1492/LT1493 will operate on any supply greater than

2.5Vandlessthan36Vtotal, andarespecifiedonsingle3.3V,

single 5V and ±15V supplies. Even with their low quiescent

supply current the minimum output drive is 20mA, ideal for

driving low impedance loads.

■

Low Input Noise Current: 0.14pA/√Hz

■

Large Output Drive Current: 20mA Min

■

Single Supply Operation

Input Voltage Range Includes Ground

Output Swings to Ground While Sinking Current

■

Wide Supply Voltage Range: 2.5V to 36V

The inputs can be driven beyond the supplies without

damage or phase reversal of the output. The low operating

voltage and wide input and output range make the LT1492/

LT1493 amplifiers ideal for battery-powered applications.

■

Specified on 3.3V, 5V and ±15V

■

Dual in 8-Pin PDIP and SO Package

■

Quad in a Narrow 16-Pin SO Package

For applications requiring faster precision single supply

amplifiers, see the 14MHz, 7V/µs LT1211/LT1212, the

28MHz, 12V/µs LT1213/LT1214 or the 23MHz, 50V/µs

LT1215/LT1216.
