TC1043 - Linear Building Block. Low-Power Voltage Reference Dual Op-Amp, Dual Compare, and Shutdown Mode
General description
The TC1043 is a mixed function device combining two general purpose operational amplifiers, two general purpose comparators, and a 16 reference voltage pin package. This increased integration enables users to replace two or three packs, saving space, reducing supply current, and improving system performance. Shut down the input, place SHDN, disable the op amp and a comparator, and place the output in a high impedance state. A comparator reference and stay active in shutdown mode. Standby power consumption typically consumes 6µA. Both op amps and comparators have rail-to-rail inputs and outputs, allowing operation from large input and output signal swings to low supply voltages. In a 16-pin QSOP package, the TC1043 is ideal for applications requiring high integration, small size, and low power consumption.
Features • Combines two, two comparators and operational amplifier voltage reference in a single package • Optimized for single supply operation • Small package: 16-pin QSOP package • Ultra-low input bias current: less than 100Pa
• Low quiescent current: 16μA (typ) for operation and 6μA (typ) for shutdown
• Rail-to-rail input and output • OperatesDowntoVDD=1.8
• The reference and a comparator remain active to provide a monitoring function off
Applications • Power Management Circuits • Battery Powered Equipment • Consumer Products • Replacement Discrete Components
