The LTC
®
1051/LTC1053 are high performance, low cost
dual/quad zero-drift operational amplifiers. The unique
achievement of the LTC1051/LTC1053 is that they integrate
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.
The LTC1051/LTC1053 have an offset voltage of 0.5µV,
drift of 0.01µV/°C, DC to 10Hz, input noise voltage typically
1.5µV
P-P
and 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.
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.
