Linear Technology Corp. (Milpitas, CA) introduced the LT1389 nanopower precision shunt voltage reference. The bandgap reference uses trimmed precision thin-film resistors to achieve 0.05 percent initial voltage accuracy.
The device features guaranteed 800nA operation and low temperature cycling hysteresis. Applications include portable meters, precision regulators, a/d and d/a converters and calibrators. The LT1389 is offered in an 8-lead SO package and comes in 1.25V or 2.5V output voltage version, each available in A and B grades.
In 1000-piece quantities, pricing begins at $3.10.
