What are the key features of ADS823EG4?
- 10-bit parallel ADC with both differential and single-ended input modes covering 1.5 V to 3.5 V analog range for flexible signal-chain design
- 100 µs maximum conversion time with parallel output bus enabling high-speed data transfer to DSPs and FPGAs without serial deserialization latency
- 28-pin SSOP package with lead-free construction supporting cost-effective, compact data-acquisition board layouts in industrial and imaging systems
What is ADS823EG4 used for?
The ADS823EG4 is suited for imaging sensor digitization, ultrasound front-ends, and high-speed data-acquisition systems that require fast 10-bit parallel output for direct interface to FPGAs or DSP data buses. Its differential input mode provides common-mode noise rejection in electrically noisy industrial environments, making it effective for CCD line-scan camera digitizers and medical ultrasound receivers. The 1.5 V to 3.5 V analog input range also accommodates low-voltage sensor outputs commonly found in industrial process-control and test-and-measurement instrumentation.

Frequently Asked Questions
What analog input voltage range and resolution does the ADS823EG4 support for signal-chain design?
The ADS823EG4 accepts analog input voltages from 1.5 V to 3.5 V in both differential and single-ended configurations, providing 10-bit resolution. This 2 V input window suits low-voltage sensor outputs and AC-coupled RF detector signals, while the 10-bit digital output delivers 1,024 quantization steps sufficient for imaging and audio digitization applications without an amplification stage.
How does the parallel output interface of ADS823EG4 benefit FPGA-based data-acquisition designs versus serial ADCs?
The ADS823EG4 delivers 10-bit conversion results directly on a parallel output bus, eliminating the deserialization logic required by SPI or I2C ADCs. In FPGA-based designs, the parallel interface allows the full 10-bit sample to be latched in a single clock cycle, reducing acquisition latency to under 100 µs and simplifying timing closure compared to serial-stream alternatives that require shift registers.
Which imaging or medical ultrasound designs are a strong fit for the ADS823EG4's differential input mode?
CCD line-scan cameras, medical ultrasound receivers, and industrial inspection systems benefit from the ADS823EG4's differential input, which cancels common-mode interference injected by ground loops or nearby switching supplies. The 10-bit depth provides 60 dB dynamic range suitable for capturing echographic signals, and the 28-pin SSOP footprint fits densely packed analog front-end PCBs in portable ultrasound probes and machine-vision modules.
What is the maximum conversion time of ADS823EG4, and how does it affect throughput in a continuous sampling loop?
The ADS823EG4 has a maximum conversion time of 100 µs, which corresponds to a worst-case sample rate of 10 kSPS in a continuous loop. For higher-throughput applications requiring hundreds of kilosamples per second, a pipelined ADC may be more appropriate; however, for imaging row-readout or low-to-medium speed process-control measurements, the 100 µs conversion fits comfortably within typical scan-line timing budgets without clock-stretching the parallel output interface.
