Description : Chopper-Stabilized Operational Amplifier

GENERAL DESCRIPTION
The TC7650 CMOS Chopper-Stabilized Operational Amplifier practically removes offset voltage error terms from system error calculations. The 5µV maximum VOS specification, for example, represents a 15 times improvement over the industry-standard OP07E. The 50nV/°C offset drift specification is over 25 times lower than the OP07E. The increased performance eliminates VOS trim procedures, periodic potentiometer adjustment and the reliability problems caused by damaged trimmers,

DESCRIPTION
The LTC®1051/LTC1053 are high performance, low cost dual/quad zero-drift Operational Amplifiers.

The slew rate of 4V/µs and gain bandwidth product of 2.5MHz are achieved With only 1mA of supply current per op amp. 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.
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.
