GENERAL INFORMATION
rail−to−rail output amplifier that features guaranteed sub
one volt operation. This unique feature set is achieved with
the use of a modified analog CMOS process that allows the
implementation of depletion MOSFET devices. The
amplifier has a 1.0 MHz gain bandwidth product, 1.2 V/ms
slew rate and is operational over a power supply range less
than 0.9 V to as high as 7.0 V.
Inputs
unconventional when compared to most low voltage
operational amplifiers. It consists of an N−channel depletion
mode differential transistor pair that drives a folded cascade
stage and current mirror. This configuration extends the
input common mode voltage range to encompass the V
and V
combined total of less than 0.9 volts. Figures 27, 28 and 29
show the input common mode voltage range versus power
supply voltage.
minimize offset voltage. The N−channel depletion mode
MOSFET input stage exhibits an extremely low input bias
current of less than 10 pA. The input bias current versus
temperature is shown in Figure 4. Either one or both inputs
can be biased as low as V
7.0 V without causing damage to the device. If the input
common mode voltage range is exceeded, the output will not
display a phase reversal. If the maximum input positive or
negative voltage ratings are to be exceeded, a series resistor
must be used to limit the input current to less than 2.0 mA.
