ADR395屬于集成電路（IC）的電壓基準(zhǔn)。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADR395電壓基準(zhǔn)產(chǎn)品屬于基準(zhǔn)電壓源系列，可通過相對較不穩(wěn)定的電源提供穩(wěn)定的電勢，電壓值始終保持恒定，以便在測量、控制和類似應(yīng)用中用作比較的標(biāo)準(zhǔn)。其功能行為可能與用于大功率調(diào)節(jié)的線性穩(wěn)壓器相似，但基準(zhǔn)電壓源器件卻不適合用于此類用途。用作比較標(biāo)準(zhǔn)時，若輸出電流容量或?qū)嶋H負(fù)載電流增大，其性能通常會降低。

GENERAL DESCRIPTION

The AD5762R is a dual, 16-bit, serial input, bipolar voltage output DAC that operates from supply voltages of ±11.4 V to ±16.5 V. Nominal full-scale output range is ±10 V. The AD5762R provides integrated output amplifiers, reference buffers, and proprietary power-up/power-down control circuitry. The device also features a digital input/output port, programmed via the serial interface, and an analog temperature sensor. The device incorporates digital offset and gain adjust registers per channel.
