ADC0804S040

ADC0804S030/040/050 Rev. 02 — 14 August 2008 www.DataSheet4U.com Single 8 bits ADC, up to 30 MHz, 40 MHz or 50 MHz Product data sheet 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. 2.
