LTC1051/LTC1053

Dual/Quad Precision

Zero-Drift Operational Amplifiers

With Internal Capacitors

FEATURES

DESCRIPTIO

■

Dual/Quad Low Cost Precision Op Amp

The LTC^®1051/LTC1053 are high performance, low cost

dual/quad zero-drift operational amplifiers. The unique

achievementoftheLTC1051/LTC1053isthattheyintegrate

on chip the sample-and-hold capacitors usually required

externally by other chopper amplifiers. Further, the

LTC1051/LTC1053 offer better combined overall DC and

AC performance than is available from other chopper

stabilized amplifiers with or without internal sample/hold

capacitors.

■

No External Components Required

■

Maximum Offset Voltage: 5µV

■

Maximum Offset Voltage Drift: 0.05µV/°C

■

Low Noise 1.5µV_P-P(0.1Hz to 10Hz)

■

Minimum Voltage Gain: 120dB

■

Minimum PSRR: 120dB

■

Minimum CMRR: 114dB

■

Low Supply Current: 1mA/Op Amp

■

Single Supply Operation: 4.75V to 16V

The LTC1051/LTC1053 have an offset voltage of 0.5µV,

driftof0.01µV/°C,DCto10Hz,inputnoisevoltagetypically

1.5µV_P-Pand typical voltage gain of 140dB. The slew rate

of 4V/µs and gain bandwidth product of 2.5MHz are

achieved with only 1mA of supply current per op amp.

■

Input Common Mode Range Includes Ground

■

Output Swings to Ground

Typical Overload Recovery Time: 3ms

■

Pin Compatible with Industry Standard Dual and

Quad Op Amps

Overload recover times from positive and negative

saturation conditions are 1.5ms and 3ms respectively,

about a 100 or more times improvement over chopper

amplifiers using external capacitors.

APPLICATIO S

■

Thermocouple Amplifiers

■

Electronic Scales

■

The LTC1051 is available in an 8-lead standard plastic

dual-in-line package as well as a 16-pin SW package. The

LTC1053 is available in a standard 14-pin plastic package

and an 18-pin SO. The LTC1051/LTC1053 are plug in

replacements for most standard dual/quad op amps with

improved performance.
