ADT7519ARQ-REEL7中文资料亚德诺数据手册PDF规格书

GENERAL DESCRIPTION

The ADT7516/ADT7517/ADT75191 combine a 10-bit temperature-to-digital converter, a 10-bit 4-channel ADC, and a quad 12-/10-/8-bit DAC, respectively, in a 16-lead QSOP package. The parts also include a band gap temperature sensor and a 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25°C.
