LINEAR BUILDING BLOCK – VOLTAGE REFERENCE, DUAL OP AMP,
DUAL COMPARATOR WITH SHUTDOWN MODE
FEATURES
GENERAL DESCRIPTION
■ Combines Two Op Amps, Two Comparators and a
Voltage Reference into a Single Package
■ Optimized for Single Supply Operation
■ Small Package .......... 16-Pin SOIC or DIP (Narrow)
■ Ultra Low Input Bias Current ...... Less than 100pA
■ Low Quiescent
Current.....................10µA, 5µA in Shutdown Mode
■ Reference and One Comparator Remain Active in
Shutdown to Provide Supervisory Functions
The TC43 is a mixed-function device combining two
general purpose op amps, two general purpose compara-
tors and a voltage reference in a single 16-pin package.
This increased integration allows the user to replace
two or three packages, saving space, lowering supply
current, and increasing system performance. A Shutdown
input, SHDN, disablestheopampsandoneofthecompara-
tors, placing their outputs in a high-impedance state. The
reference and one comparator stay active in Shutdown
Mode. Standby power consumption is typically 5µA.
The TC43 is designed specifically for operation from a
single supply, however, operation from dual supplies is also
possible, and the power supply current drain is independent
of the magnitude of the power supply voltage.
APPLICATIONS
■ Power Supply Circuits
■ Embedded Systems
■ Instrumentation
■ Portable Equipment
■ Consumer Products
Packaged in a 16-pin narrow SOIC (0.150 wide) or
16-pin DIP, the TC43 is ideal for applications requiring high
integration, small size and low power.
■ Replacements for Discrete Components
