ADC08B200集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADC08B200属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADC08B200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 ADC08B200 is a high speed analog-to-digital

converter (ADC) with an integrated capture buffer.

The 8-bit, 200 MSPS A/D core is based upon the

proven ADC08200 with integrated track-and-hold and

is optimized for low power consumption. This device

contains a selectable size capture buffer of up to 1,024 bytes that allows fast capture of an input signal

with a slower readout rate. An on-chip clock PLL

circuit provides the option of on-chip clock rate

multiplication to provide the high speed sampling

clock.

The ADC08B200 is resistant to latch-up and the

outputs are short-circuit proof. The top and bottom of the ADC08B200's reference ladder are available for

connections, enabling a wide range of input

possibilities. The digital outputs are TTL/CMOS

compatible with a separate output power supply pin

to support interfacing with 2.7V to 3.3V logic. The

digital inputs and outputs are low voltage TTL/CMOS

compatible and the output data format is straight

binary.

The ADC08B200Q runs on an Automotive Grade

Flow and is AEC-Q100 Grade 2 Qualified.

The ADC08B200 is offered in a 48-pin plastic

package (TQFP) and is specified over the extended

industrial temperature range of −40°C to +105°C. An

evaluation board is available to assist in the easy

evaluation of the ADC08B200.
