LINEAR BUILDING BLOCK – VOLTAGE REFERENCE, DUAL OP AMP, DUAL COMPARATOR WITH SHUTDOWN MODE PRELIMINARY INFORMATION GENERAL DESCRIPTION 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, disables the op amps and one of the compara- 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. 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.

The TC43 minimum operating voltage is 1.8V and maximum supply current is only 15µA (fully enabled). It combines two comparators, two op amps and a voltage reference in a single package. A shutdown mode is incorporated for easy adaptation to system power manage- ment schemes. During shutdown, all but one comparator and the voltage reference are disabled (i.e. powered down and with their respective outputs at high impedance). The “still awake” comparator and voltage reference can be used as wake-up timer, power supply monitor, LDO controller or other continuous duty circuit function. Operational Amplifiers Both op amps have rail-to-rail outputs, and an input common range that includes ground. Input offset voltage is 1.0mV and input bias current is only 50pA. The outputs are protected against short circuits. Both op amps are disabled (powered down and outputs at high impedance) during shutdown. Comparators Both comparators feature complimentary outputs with current sinking capability of 2.5mA. Inputs and outputs are rail-to-rail. Comparator CMPTR1 is disabled (powered down and outputs at high impedance) during shutdown. CMPTR2 remains fully enabled during shutdown. NOTES: 1. The reference and one comparator remain active in SHUTDOWN mode. 2. Op Amp configured as a voltage follower (inverting input connected to output; signal applied to non-inverting input). 3. Input common-mode voltage should not be allowed to go negative by more than 0.3V. 4. V DD = 5.0V; CL = 100pF. 5. Guaranteed by Design
