GENERAL DESCRIPTION
The ALD1722E is a monolithic rail-to-rail precision CMOS operational
amplifier with integrated user programmable EPAD (Electrically Program-
mable Analog Device) based offset voltage adjustment. The ALD1722E
is a direct replacement of the ALD1712 operational amplifier, with the
added feature of user-programmable offset voltage trimming resulting in
significantly enhanced total system performance and user flexibility.
EPAD technology is an exclusive ALD design which has been refined for
analog applications where precision voltage trimming is necessary to
achieve a desired performance.
It utilizes CMOS FETs as in-circuit
elements for trimming of offset voltage bias characteristics with the aid of
a personal computer under software control. Once programmed, the set
parameters are stored indefinitely within the device even after power-
down. EPAD offers the circuit designer a convenient and cost-effective
trimming solution for achieving the very highest amplifier/system perfor-
mance.
The ALD1722E operational amplifier features rail-to-rail input and output
voltage ranges, tolerance to over-voltage input spikes of 300mV beyond
supply rails, high capacitive loading up to 4000pF, extremely low input
currents of 0.01pA typical, high open loop voltage gain, useful bandwidth
of 1.5MHz, slew rate of 2.1V/
s, and low supply current of 0.8mA.
