ADS1606IPAPR集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS1606IPAPR属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS1606IPAPR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 ADS1605 and ADS1606 are high-speed, high-precision,

delta-sigma analog-to-digital converters (ADCs)

with 16-bit resolution. The data rate is 5 mega-samples

per second (MSPS), the bandwidth (−3dB) is 2.45MHz,

and passband ripple is less than ±0.0025dB (to

2.2MHz). Both devices offer the same outstanding performance

at these speeds with a signal-to-noise ratio up

to 88dB, total harmonic distortion down to −99dB, and

a spurious-free dynamic range up to 101dB. For even

higher-speed operation, the data rate can be doubled to

10MSPS in 2X mode. The ADS1606 includes an adjustable

first-in first-out buffer (FIFO) for the output data.

The input signal is measured against a voltage reference

that can be generated on-chip or supplied externally.

The digital output data are provided over a simple

parallel interface that easily connects to digital signal

processors (DSPs). An out-of-range monitor reports

when the input range has been exceeded. The

ADS1605/6 operate from a +5V analog supply (AVDD)

and +3V digital supply (DVDD). The digital I/O supply

(IOVDD) operates from +2.7 to +5.25V, enabling the

digital interface to support a range of logic families. The

analog power dissipation is set by an external resistor

and can be reduced when operating at slower speeds.

A power down mode, activated by a digital I/O pin, shuts

down all circuitry. The ADS1605/6 are offered in a

TQFP-64 package using TI PowerPAD technology.

The ADS1605 and ADS1606, along with their 18-bit

counterparts, the ADS1625 and ADS1626, are well

suited for the demanding measurement requirements

of scientific instrumentation, automated test equipment,

data acquisition, and medical imaging.
