ADS823E - 10-Bit 60-MSPS ADC | Texas Instruments
MPN： ADS823E ✗ 停產ADS823E 概覽
An ADC is a data-converter IC that samples an analog voltage and produces its corresponding digital code. The ADS823E belongs to the pipeline ADC class within the broader data-converter and signal-processing hierarchy. Pipeline conversion separates sampling and conversion stages, supporting high sampling rates for communications, instrumentation, imaging, and control systems while requiring careful clock, reference, input, and digital-interface design.
Verified features include 60 dB signal-to-noise ratio, 74 dBFS spurious-free dynamic range, 265 mW power consumption, programmable input range, power-down capability, and low differential nonlinearity of 0.25 LSB. The dual input capability allows the converter to work with single-ended sources or differential signals. The internal/external reference option gives designers flexibility in analog calibration and system-level voltage-reference planning.
The device uses a single-ended analog input or differential input arrangement and supports single +5 V analog-supply operation with +3 V or +5 V-compatible logic levels. Its 10-bit resolution gives 1024 digital codes, while the 60-MSPS sampling rate supports high-speed acquisition. The 28-SSOP package is a surface-mount gull-wing package, but the verified snippets do not provide its exact dimensions.
Typical uses include communications receivers, medical imaging instrumentation, industrial data acquisition, signal monitoring, and embedded control systems where a compact high-speed ADC is required. The parallel output requires a 10-bit data bus plus associated clock and control signals, so the surrounding digital system must be designed for the converter's timing and voltage requirements.
Designers should use the manufacturer datasheet for the complete pinout, timing, electrical limits, reference recommendations, and layout requirements. Because the supplied evidence does not include complete pricing, stock, lead-time, or all pin-level details, those items remain explicitly marked or unavailable rather than inferred.

典型應用
ADS823E 適用於 6 應用s: Communications Receiver Front End, Medical Imaging Instrumentation, Industrial Data Acquisition, Power and Motor Monitoring, Communications Baseband Processing, Embedded Test and Measurement.
Communications Receiver Front End
The ADS823E fits communications receiver designs that need 60-MSPS sampling and 10-bit resolution. Its single-ended or differential input support lets the converter accept either a conditioned receiver signal or a balanced mixer output, while the programmable input range helps align the ADC with the available signal amplitude. The verified 60 dB SNR and 74 dBFS SFDR provide useful starting points for receiver dynamic-range analysis. In implementation, keep the analog path short, control clock jitter, and use the datasheet reference and decoupling recommendations. A 60-MSPS converter does not automatically guarantee useful RF bandwidth; antenna filtering, gain control, mixer performance, and clock quality must also meet the system requirements.
推薦
Medical Imaging Instrumentation
The ADS823E is appropriate for medical imaging instrumentation when a 10-bit, 60-MSPS ADC is sufficient for digitizing a prepared analog signal. The 265 mW verified power specification is useful when balancing acquisition performance against thermal budget, while the 28-SSOP package supports compact surface-mount construction. Differential operation can simplify rejection of common-mode noise when the sensor or amplifier stage is balanced. However, medical systems require application-specific validation of signal integrity, isolation, patient protection, latency, calibration, and regulatory compliance. The ADC itself does not establish medical compliance; designers must review the complete analog front end and system risk controls.
推薦
Industrial Data Acquisition
The ADS823E is suitable for industrial data-acquisition modules that need to sample dynamic control or diagnostic signals at up to 60 MSPS. Its 10-bit output provides 1024 digital codes, while the parallel interface makes it practical for FPGA, DSP, or microcontroller-adjacent acquisition systems when timing is carefully managed. The single +5 V analog supply and +3 V/+5 V-compatible logic capability help bridge power domains in mixed-signal equipment. In a deployed system, verify input bandwidth, acquisition latency, clock stability, and isolation requirements. For lower-data-rate sensors, a slower ADC may reduce power and simplify processing while preserving sufficient accuracy.
推薦
Power and Motor Monitoring
ADS823E can support fast monitoring of power-converter waveforms, motor-control signals, and inverter feedback when the input bandwidth and timing requirements match its 60-MSPS sampling capability. A programmable input range allows the analog conditioning stage to use the ADC range efficiently, while power-down capability can help manage system power states where supported by the complete design. Differential input is valuable when sensing nodes include substantial common-mode voltage. The designer must still ensure that the front end protects the ADC, filters aliasing components, and supplies a clean reference. Use the datasheet's absolute maximum ratings and recommended operating conditions before selecting resistor dividers or amplifiers.
推薦
Communications Baseband Processing
The ADS823E can digitize baseband waveforms in communications equipment when 10-bit resolution and 60-MSPS sampling provide adequate margin. Its differential input option helps preserve signal quality when the RF or IF stage produces balanced signals, and the reported 60 dB SNR and 74 dBFS SFDR help quantify quantization noise and harmonic performance in initial system studies. The ADC should be paired with careful low-noise amplification, controlled clock routing, and a stable reference. Parallel outputs require a receiving FPGA or DSP with compatible voltage levels and enough board-routing margin. Validate gain distribution, spectral masks, intermodulation, and latency in the complete signal chain rather than selecting the converter from resolution alone.
推薦
Embedded Test and Measurement
The ADS823E can serve as the conversion element in compact oscilloscope-like, waveform, or automated test equipment that samples signals at up to 60 MSPS. The 10-bit parallel output is manageable in FPGA-based acquisition hardware when the clock and data buses are routed with short traces and controlled timing. The 265 mW figure provides a starting point for power planning, but actual consumption depends on clocking, I/O activity, supply choices, and power-down behavior. Add an analog protection network, anti-alias filter, stable reference, and calibration path. For slower instruments, verify whether the extra speed is needed; otherwise, a lower-power converter may reduce heat, cost, and design complexity.

主要差異化特點
- High-speed pipeline conversion (對比ADS825E)

- Documented performance figures (對比ADS826)
- Single +5 V analog supply architecture (對比ADS824)
設計說明
The verified specifications identify a 60-MSPS pipeline ADC with 60 dB SNR and 74 dBFS SFDR. Route the analog input, reference, and clock signals with short paths and controlled return currents, and place input and reference decoupling close to the relevant pins according to the manufacturer datasheet. Differential input can reduce susceptibility to common-mode noise, but balance the input network and verify timing and settling behavior with the complete clock scheme.
The verified power figure is 265 mW, but system power depends on clock rate, I/O activity, reference mode, and power-down state. Begin power-budget calculations with the verified figure and then measure the implemented board at the intended sampling rate. Keep the analog supply and digital interface rails compatible with the datasheet limits, and avoid allowing supply noise or ground bounce to degrade SNR and conversion timing.
The ADS823E is a 28-pin SSOP surface-mount device. Preserve pin-to-pin layout reuse only after confirming that any replacement has identical pin assignments and package dimensions. Keep the 10-bit parallel bus and clock routing compact, provide a solid return path, and separate high-speed digital activity from sensitive analog inputs. Verify the complete manufacturer package drawing before releasing the PCB footprint.
Do not treat the ADC's 60-MSPS sampling rate as an unlimited input bandwidth. Apply an appropriate anti-alias filter, verify source impedance and settling time, and confirm the analog input range before applying large signals. The programmable input range is useful only when the complete front end keeps the signal within the converter's specified operating region. Obtain the full datasheet for pinout, absolute maximum ratings, and timing margins.
