Although supply current is only 340µA, a novel output
stage can source or sink in excess of 20mA while retaining
high voltage gain. Common mode input range includes
ground to accommodate low ground-referenced inputs
from strain gauges or thermocouples, and output can
swing to within a few millivolts of ground. If a higher
slew rate (in excess of 1V/µs) or micropower operation
(supply current down to 90µA) is required, the operating
currents can be modified by connecting an external
optional resistor to Pin 8.
Better than OP-07: 0.07pA/√Hz at 10Hz
High Input Impedance: 250MΩ Min
Minimum Supply Voltage: 2.7V Min
