ADS7806UB集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS7806UB属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS7806UB模数转换器（ADC）模数转换器（ADC、A/D 或 A 转 D）对模拟信号进行采样，例如由麦克风采集的声音或传感器的输出，然后将其转换为数字信号。一般来说，数字输出是二进制补码二进制数，与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构（例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式）进行选择。

DESCRIPTION

The ADS7806 is a low-power, 12-bit, sampling Analog-to-

Digital (A/D) converter using state of the art CMOS structures.

It contains a complete 12-bit, capacitor-based, Successive

Approximation Register (SAR) A/D converter with sampleand-

hold, clock, reference, and a microprocessor interface with

parallel and serial output drivers.

The ADS7806 can acquire and convert to full 12-bit accuracy

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 ADS7806 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.
