ADC0804S040/DB 产品手册 - NXP（恩智浦）

1. 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.

The device requires an external source to drive its reference ladder. If the application

requires that the reference is driven via internal sources, NXP recommends you use one

of the ADC1003S030/040/050 family.
