Analog Devices Inc. AD7356YRUZ-500RL7

Overview

AD7356YRUZ-500RL7 from Analog Devices is a dual, 12-bit, successive approximation register (SAR) ADC with simultaneous sampling, 5 MSPS per channel throughput, differential input architecture, on-chip 2.048 V reference, and operation across −40°C to +125°C. It serves as a high-speed data acquisition front-end in motion control feedback loops and I/Q demodulation signal chains.

For engineers reviewing the AD7356YRUZ-500RL7 datasheet, AD7356YRUZ-500RL7 pinout, AD7356YRUZ-500RL7 application, or AD7356YRUZ-500RL7 equivalent, key selection considerations include dual-channel simultaneity, 71.5 dB typical SNR at 1 MHz, 110 MHz full-power bandwidth, 40 ps aperture delay match, and SPI-compatible serial interface with separate SDATAA/SDATAB outputs.

Technical Context

The AD7356YRUZ-500RL7 integrates two independent SAR ADCs, each with a dedicated track-and-hold amplifier supporting >110 MHz analog input bandwidth and 30 ns acquisition time for full-scale steps. Its conversion is initiated on the falling edge of CS, with timing fully governed by SCLK frequency (up to 80 MHz).

It employs capacitive DAC-based successive approximation with no pipeline latency, delivering deterministic 13-clock-cycle conversion time plus t2 setup. The device supports three power modes-normal (36 mW), partial power-down (9.5 mW), and full power-down (16 μW)-enabling dynamic throughput/power trade-offs in real-time systems.

Key Specifications

Pinout & Package

FAQ

What is the maximum analog input frequency supported by the AD7356YRUZ-500RL7?

The AD7356YRUZ-500RL7 supports a full-power bandwidth of 110 MHz at the −3 dB point and 77 MHz at the −0.1 dB point, enabling accurate digitization of high-frequency signals such as motor phase currents or IF signals in communication receivers. This bandwidth is maintained under simultaneous dual-channel operation with no degradation in SNR or THD performance.

Does the AD7356YRUZ-500RL7 require an external reference voltage?

No, the AD7356YRUZ-500RL7 includes a precision on-chip 2.048 V reference with ±0.25% initial accuracy and 6 ppm/°C temperature coefficient, sufficient for most high-speed measurement applications. External reference can be applied via REFA/REFB pins if tighter tolerance or custom voltage is needed, but the internal reference eliminates BOM and layout overhead for standard use cases.

How does the AD7356YRUZ-500RL7 handle simultaneous sampling across both channels?

The AD7356YRUZ-500RL7 uses independent track-and-hold amplifiers for each channel, triggered synchronously by the falling edge of the CS signal. Aperture delay match is specified at 40 ps, ensuring sub-degree phase alignment between sampled waveforms at frequencies up to 100 MHz-critical for vector calculations and coherent signal processing in the AD7356YRUZ-500RL7.

What serial interface protocols does the AD7356YRUZ-500RL7 support?

The AD7356YRUZ-500RL7 features an SPI-compatible serial interface that operates with standard SPI, QSPI™, MICROWIRE™, and DSP-compatible timing. It supports MSB-first 12-bit data transmission on dual SDATAA/SDATAB lines or sequentially on one line, with configurable frame length (14 or 16 SCLK cycles) and no requirement for external framing logic in the AD7356YRUZ-500RL7.

Is the AD7356YRUZ-500RL7 suitable for automotive under-hood applications?

Yes, the AD7356YRUZ-500RL7 is rated for −40°C to +125°C operation (Y-grade), has robust ESD protection (1.5 kV HBM), and meets stringent industrial reliability standards. Its TSSOP package, 2.5 V single-supply operation, and integrated reference make it suitable for engine control units, battery management systems, and other automotive under-hood applications where the AD7356YRUZ-500RL7 delivers deterministic timing and thermal stability.
