描述 Description

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.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.
