TYPICAL PERFORMANCE CHARACTERISTICS
APPLICATIONS
10
The LT1078/LT1079 devices are fully specified with
V
conditions appears to be the most representative for
battery-powered micropower circuits. Offset voltage is
internally trimmed to a minimum value at these supply
voltages. When 9V or 3V batteries or 2.5V dual supplies
are used, bias and offset current changes will be minimal.
Offset voltage changes will be just a few microvolts as
given by the PSRR and CMRR specifications. For example,
if PSRR = 114dB (= 2 V/V), at 9V the offset voltage change
will be 8 V. Similarly, V
to a common mode voltage change of 2.4V or a V
change of 7 V if CMRR = 110dB (3 V/V).

Single Supply Operation
The LT1078/LT1079 are fully specified for single supply
operation, i.e., when the negative supply is 0V. Input
common mode range goes below ground and the output
swings within a few millivolts of ground while sinking
current. All competing micropower op amps either cannot
swing to within 600mV of ground (OP-20, OP-220, OP-420)
or need a pull-down resistor connected to the output to swing
to ground (OP-90, OP-290, OP-490, HA5141/42/44). This
