ADS5560IRGZR集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS5560IRGZR属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS5560IRGZR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。

3 Description

The ADS556x is a high-performance 16-bit family of

ADCs with sampling rates up to 80 MSPS. The

device supports very-high SNR for input frequencies

in the first Nyquist zone. The device includes a lowfrequency

noise suppression mode that improves the

noise from DC to about 1 MHz.

In addition to high performance, the device offers

several flexible features such as output interface

(either Double Data Rate [DDR] LVDS or parallel

CMOS) and fine gain in 1-dB steps until 6-dB

maximum gain.

Innovative techniques, such as DDR LVDS and an

internal reference that does not require external

decoupling capacitors, have been used to achieve

significant savings in pin count. This innovation

results in a compact 7-mm × 7-mm 48-pin VQFN

package.

The device can be put in an external reference mode,

where the VCM pin behaves as the external reference input. For applications where power is

important, the ADS556x device offers power down

modes and automatic power scaling at lower sample

rates.

The device is specified over the industrial

temperature range of –40°C to 85°C.
