APPLICATIONS INFORMATION
WU
U
The LT1078/LT1079 devices are fully specified with
V + = 5V, V = 0V, VCM = 0.1V. This set of operating
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
μV/V), at 9V the offset voltage change
will be 8
μV. Similarly, VS = ±2.5V, VCM = 0V is equivalent
to a common mode voltage change of 2.4V or a VOS
change of 7
μV if CMRR = 110dB (3μV/V).
A full set of specifications is also provided at
±15V supply
voltages for comparison with other devices and for com-
pleteness.
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
