TLC1551IDWR集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

TLC1551IDWR属于集成电路（IC）的模数转换器（ADC）。由美国德州仪器公司制造生产的TLC1551IDWR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 TLC1550x and TLC1551 are data acquisition

analog-to-digital converters (ADCs) using a 10-bit,

switched-capacitor, successive-approximation network.

A high-speed, 3-state parallel port directly

interfaces to a digital signal processor (DSP) or

microprocessor (μP) system data bus. D0 through

D9 are the digital output terminals with D0 being

the least significant bit (LSB). Separate power

terminals for the analog and digital portions

minimize noise pickup in the supply leads.

Additionally, the digital power is divided into two

parts to separate the lower current logic from the

higher current bus drivers. An external clock can be

applied to CLKIN to override the internal system

clock if desired.

The TLC1550I and TLC1551I are characterized for

operation from −40°C to 85°C. The TLC1550M is

characterized over the full military range of −55°C

to 125°C.
