LTC1052/LTC7652

Zero-Drift

Operational Amplifier

FEATURES

DESCRIPTIO

The LTC^®1052 and LTC7652 are low noise zero-drift op

amps manufactured using Linear Technology’s enhanced

LTCMOS^TMsilicon gate process. Chopper-stabilization

constantlycorrectsoffsetvoltageerrors.Bothinitialoffset

and changes in the offset due to time, temperature and

common mode voltage are corrected. This, coupled with

picoampere input currents, gives these amplifiers

unmatched performance.

■

Guaranteed Max Offset: 5µV

■

Guaranteed Max Offset Drift: 0.05µV/°C

■

Typ Offset Drift: 0.01µV/°C

■

Excellent Long Term Stability: 100nV/√Month

■

Guaranteed Max Input Bias Current: 30pA

■

Over Operating Temperature Range:

Guaranteed Min Gain: 120dB

Guaranteed Min CMRR: 120dB

Guaranteed Min PSRR: 120dB

Low frequency (1/f) noise is also improved by the

chopping technique. Instead of increasing continuously

ata3dB/octaverate, theinternalchoppingcausesnoiseto

decrease at low frequencies.

■

Single Supply Operation: 4.75V to 16V

(Input Voltage Range Extends to Ground)

External Capacitors can be Returned to V^–with No

■

Noise Degradation

The chopper circuitry is entirely internal and completely

transparent to the user. Only two external capacitors

are required to alternately sample-and-hold the offset

correction voltage and the amplified input signal. Control

circuitry is brought out on the 14-pin and 16-pin versions

to allow the sampling of the LTC1052 to be synchronized

with an external frequency source.
