Programmable Signal Enables Flexible ADC

NXP Semiconductors’ ADC0808S ADC generates a programmable Complete Conversion Signal (CCS) that allows both the delay time and the frequency of the acquisition clock to be adjusted. This enables the implementation of flexible acquisition control systems.

NXP’s ADC0808S is a differential, high-speed, 8-bit ADC optimised for telecommunication transmission-control systems and tape-drive applications. The ADC’s clock inputs are selectable for 1.8V CMOS signals or Low-Voltage Differential Signals (LVDS). The data-output signal levels and all static digital inputs are 1.8V CMOS compatible.

The ADC0808S is supplied in an HTQFP48 package, with a sampling rate of up to 250MHz and a maximum analogue input frequency of 560MHz.
