HCA10014
15MHz, BiMOS Operational Amplifier with
MOSFET Input/CMOS Output
HCA10014 op amp combines the advantage of both CMOS
and bipolar transistors.
Gate protected P-Channel MOSFET (PMOS) transistors are
used in the input circuit to provide very high input
impedance, very low input current, and exceptional speed
performance. The use of PMOS transistors in the input stage
results in common mode input voltage capability down to
0.5V below the negative supply terminal, an important
attribute in single supply applications.
A CMOS transistor pair, capable of swinging the output
voltage to within 10mV of either supply voltage terminal (at
very high values of load impedance), is employed as the
output circuit.
The HCA10014 operates at supply voltages ranging from 5V
to 16V, (
±
2.5V to
±
8V). It can be phase compensated with a
single external capacitor, and have terminals for adjustment
of offset voltage for applications requiring offset null
capability. Terminal provisions are also made to permit
strobing of the output stage.
