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 0.5µV,
drift of 0.01µV/°C, 0.1Hz to 10Hz input noise voltage of
1.5µV
P-P
, and a typical voltage gain of 140dB. It has a slew
rate of 3V/µs 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.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Connecting any terminal to voltages greater than V
+
or less than V
–
may cause destructive latch-up. It is recommended that no sources
operating from external supplies be applied prior to power-up of the
LTC1151.
Note 3: These parameters are guaranteed by design. Thermocouple effects
preclude measurement of these voltage levels in high speed automatic test
systems. V
OS
is measured to a limit determined by test equipment
capability.
Note 4: Current Noise is calculated from the formula:
I
N
= √(2q • I
b
)
where q = 1.6 × 10
