General description

The ADC0806030/040/050 are a family of 8-bit high-speed, low-power Analog-to-Digital Converters (ADC) for professional video and other applications. It converts the analog input signal into 8-bit binary coded digital signals at a maximum sampling rate of 50 MHz. All digital inputs and outputs are Transistor-Transistor Logic (TTL) and CMOS compatible, although a low-level sine wave clock input signal can also be used.

Features

■ 8-bit resolution

■ Sampling rate up to 50 MHz

■ One clock cycle conversion only

■ High signal-to-noise ratio over a large analog input frequency range (7.8 effective bits at 4.43 MHz full-scale input at fclk = 40 MHz)

■ No missing codes guaranteed

■ In-Range (IR) CMOS output

■ TTL and CMOS levels compatible digital inputs

■ 3 V to 5 V CMOS digital outputs

■ Low-level AC clock input signal allowed

■ External reference voltage regulator

■ Power dissipation only 175 mW (typical)

■ Video data digitizing

■ Radar

■ Transient signal analysis

■ Σ∆ modulators

■ Medical imaging

■ Barcode scanner

■ Global Positioning System (GPS) receiver

ADC0804S050属于集成电路（IC） > 模数转换器（ADC）。恩智浦半导体公司制造生产的ADC0804S050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。
