TLV0831CP集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

TLV0831CP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TLV0831CP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

These devices are 8-bit successive-approximation analog-to-digital converters. The TLV0831 has single input

channels; the TLV0832 has multiplexed twin input channels. The serial output is configured to interface with

standard shift registers or microprocessors.

The TLV0832 multiplexer is software configured for single-ended or differential inputs. The differential analog

voltage input allows for common-mode rejection or offset of the analog zero input voltage value. In addition, the

voltage reference input can be adjusted to allow encoding any smaller analog voltage span to the full 8 bits of

resolution.

The operation of the TLV0831 and TLV0832 devices is very similar to the more complex TLV0834 and TLV0838

devices. Ratiometric conversion can be attained by setting the REF input equal to the maximum analog input

signal value, which gives the highest possible conversion resolution. Typically, REF is set equal to VCC (done

internally on the TLV0832).

The TLV0831C and TLV0832C are characterized for operation from 0°C to 70°C. The TLV0831I and TLV0832I

are characterized for operation from −40°C to 85°C.
