TLC5510INS集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

TLC5510INS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TLC5510INS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 TLC5510 and TLC5510A are CMOS, 8-bit, 20

MSPS analog-to-digital converters (ADCs) that

utilize a semiflash architecture. The TLC5510 and

TLC5510A operate with a single 5-V supply and

typically consume only 130 mW of power.

Included is an internal sample-and-hold circuit,

parallel outputs with high-impedance mode, and

internal reference resistors.

The semiflash architecture reduces power

consumption and die size compared to flash

converters. By implementing the conversion in a

2-step process, the number of comparators is

significantly reduced. The latency of the data

output valid is 2.5 clocks.

The TLC5510 uses the three internal reference

resistors to create a standard, 2-V, full-scale

conversion range using VDDA. Only external jumpers are required to implement this option and eliminates the

need for external reference resistors. The TLC5510A uses only the center internal resistor section with an

externally applied 4-V reference such that a 4-V input signal can be used. Differential linearity is 0.5 LSB at 25°C

and a maximum of 0.75 LSB over the full operating temperature range. Typical dynamic specifications include

a differential gain of 1% and differential phase of 0.7 degrees.

The TLC5510 and TLC5510A are characterized for operation from –20°C to 75°C.
