Analog Devices has created an alternative to its venerable LTZ1000 untra-precision voltage reference, with better initial accuracy and less noise, although not every parameter is improved. Called ADR1000 (right), the nominally 6.62V part is a pin-compatible replacement for the LTZ1000 (below), and like it includes a buried Zener reference, a heater for temperature stabilization and ...
