TLV5580集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

TLV5580属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的TLV5580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 TLV5580 is an 8-bit 80 MSPS high-speed A/D

converter. It converts the analog input signal into

8-bit binary-coded digital words up to a sampling

rate of 80 MHz. All digital inputs and outputs are

3.3 V TTL/CMOS-compatible.

The device consumes very little power due to the

3.3 V supply and an innovative single-pipeline

architecture implemented in a CMOS process.

The user obtains maximum flexibility by setting

both bottom and top voltage references from

user-supplied voltages. If no external references

are available, on-chip references are available for

internal and external use. The full-scale range is

1 Vpp up to 1.6 Vpp, depending on the analog

supply voltage. If external references are

available, the internal references can be disabled

independently from the rest of the chip, resulting

in an even greater power saving.

While usable in a wide variety of applications, the

device is specifically suited for the digitizing of

high-speed graphics and for interfacing to LCD

panels or LCD/DMD projection modules . Other

applications include DVD read channel

digitization, medical imaging and

communications. This device is suitable for IF

sampling of communication systems using

sub-Nyquist sampling methods because of its

high analog input bandwidth.
