HCA10014

Data Sheet

August 1999

File Number

4769

15MHz, BiMOS Operational Ampli鏗乪r 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, (鹵2.5V to

鹵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.
