The LTC
1151 is a high voltage, high performance dual
zero-drift operational amplifier. The two sample-and-hold
capacitors per amplifier required externally by other chop-
per amplifiers are integrated on-chip. The LTC1151 also
incorporates proprietary high voltage CMOS structures
which allow operation at up to 36V total supply voltage.
The LTC1151 has a typical offset voltage of 0.5
V,
drift of 0.01
V/°C, 0.1Hz to 10Hz input noise voltage of
1.5
VP-P, and a typical voltage gain of 140dB. It has a slew
rate of 3V/
s and a gain-bandwidth product of 2.5MHz
with a supply current of 0.9mA per amplifier. Overload
recovery times from positive and negative saturation are
3ms and 20ms, respectively.
The LTC1151 is available in a standard 8-lead plastic DIP
package as well as a 16-lead wide body SO. The LTC1151
is pin compatible with industry-standard dual op amps
and runs from standard
±15V supplies, allowing it to plug
in to most standard bipolar op amp sockets while offering
significant improvement in DC performance.
