ADS7807中文资料低功耗 16 位采样 CMOS 模数转换器数据手册TI规格书

描述 Description

The ADS7807 is a low-power, 16-bit, sampling Analog-to-Digital (A/D) converter using state-of-the-art CMOS structures. It contains a complete 16-bit, capacitor-based, Successive Approximation Register (SAR) A/D converter with sample-and-hold, clock, reference, and microprocessor interface with parallel and serial output drivers.
The ADS7807 can acquire and convert 16-bits to within ±1.5LSB in 25µs max while consuming only 35mW max. Laser trimmed scaling resistors provide standard industrial input ranges of ±10V and 0V to +5V. In addition, a 0V to +4V range allows development of complete single-supply systems.
The ADS7807 is available in a 0.3\" DIP-28 and SO-28, both fully specified for operation over the industrial –40°C to +85°C temperature range.
