GENERAL DESCRIPTION
The TDA8798 is a dual 8-bit ADC with DPGA.
The 100 Msps maximum sampling rate and 34 dBV DPGA gain range optimizes the ADC for high dynamic range applications.

FEATURES
• Dual 8-bit Analog-to-Digital Converter (ADC)
• Sampling rate up to 100 million samples per second (Msps)
• Dual 34 dBV 6-bit Digitally Programmable Gain Amplifier (DPGA) with optional power-off
• Optional external equalization filter with capacitive coupling between DPGA and ADC
• Serial Interface (SI) for DPGA gain control using either parallel load mode or count-up/count-down mode
• 3.3 V TTL/CMOS compatible I/O
• Differential or single-ended TTL/CMOS clock interface
• AC or DC coupling for DPGA inputs.

APPLICATIONS
• High-dynamic range acquisition front-ends
• Digital data storage read channels.
