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

Key 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.
