2 / 20 page 1996 Feb 21 2 Philips Semiconductors Product specification 3.3 V, 25 MHz 8-bit analog-to-digital converter (ADC) TDA8792 FEATURES • 8-bit resolution • Sampling rate up to 25 MHz • 30 MHz input signal bandwidth (full scale) • High signal-to-noise ratio over a large analog input frequency range (7.3 effective bits at 4.43 MHz full-scale input at fclk = 25 MHz) • CMOS compatible digital inputs • External reference voltage regulator • Power dissipation only 53 mW (typical) • Standby mode (only 1.2 mW typical) • Low analog input capacitance, no buffer amplifier required • No sample-and-hold circuit required. APPLICATIONS Analog-to-digital conversion for: • General purpose • Hand-held equipment • Mobile telecommunication • Instrumentation • Video. GENERAL DESCRIPTION The TDA8792 is a 8-bit analog-to-digital converter (ADC) for low-voltage, portable applications. It operates at 3.3 V and converts the analog input signal into 8-bit binary-coded digital words at a maximum sampling rate of 25 MHz. The output data is valid after a delay of 6 clock cycles.
