Analog Devices Inc. AD7352YRUZ-500RL7

Overview

AD7352YRUZ-500RL7 from Analog Devices is a dual, 12-bit, successive approximation register (SAR) analog-to-digital converter with simultaneous sampling, 3 MSPS per channel throughput, on-chip 2.048 V reference (±0.25% at 25°C), and differential input architecture. It operates from a single 2.5 V supply, consumes 26 mW at full rate, and targets high-fidelity data acquisition in motion control and I/Q demodulation systems.

For engineers reviewing the AD7352YRUZ-500RL7 datasheet, AD7352YRUZ-500RL7 pinout, AD7352YRUZ-500RL7 application, or AD7352YRUZ-500RL7 equivalent, key selection considerations include simultaneous dual-channel sampling latency, ADC-to-ADC isolation (−100 dB), differential input common-mode range (0.5 V to 1.9 V), SPI-compatible serial interface timing, and TSSOP-16 thermal performance (θJA = 143°C/W).

Technical Context

The AD7352YRUZ-500RL7 integrates two independent SAR ADCs sharing a common SCLK and CS interface, each with its own track-and-hold amplifier supporting >110 MHz full-power bandwidth. Conversion is initiated on the falling edge of CS, with no conversion latency and deterministic timing governed by SCLK frequency (up to 48 MHz).

It employs capacitive DAC-based successive approximation with charge redistribution, uses straight binary output coding, and supports three power modes-normal (10 mA), partial power-down (4 mA), and full power-down (40 µA at −40°C to +85°C)-enabling dynamic throughput/power management in embedded systems.

Key Specifications

Pinout & Package

FAQ

What is the operating temperature range of the AD7352YRUZ-500RL7?

The AD7352YRUZ-500RL7 is rated for −40°C to +125°C operation (Y grade), making it suitable for under-hood automotive, industrial motor drives, and outdoor infrastructure applications. This extended range is validated across all electrical specifications including INL, SNR, and reference stability, with full power-down mode current specified up to 125°C.

Does the AD7352YRUZ-500RL7 require an external reference?

No, the AD7352YRUZ-500RL7 includes an integrated 2.048 V reference with ±0.25% accuracy at 25°C and 6 ppm/°C temperature coefficient. External reference is optional and only needed if tighter initial accuracy, lower drift, or different voltage (2.148 V to VDD) is required-the internal reference is accessible at REFA and REFB pins.

How does the AD7352YRUZ-500RL7 handle simultaneous sampling of two channels?

The AD7352YRUZ-500RL7 uses two independent track-and-hold amplifiers and SAR cores that sample on the same CS falling edge, ensuring zero inter-channel aperture delay mismatch (<40 ps). Conversion results appear simultaneously on SDATAA and SDATAB, eliminating time skew critical for vector measurements and phase analysis.

What serial interface protocols does the AD7352YRUZ-500RL7 support?

The AD7352YRUZ-500RL7 supports SPI, QSPI, MICROWIRE, and DSP-compatible serial interfaces via its SCLK, CS, SDATAA, and SDATAB pins. It uses standard 4-wire framing with MSB-first 14-bit output (2 leading zeros + 12 data bits), requiring no special configuration registers or command sequences for basic readout.

Can the AD7352YRUZ-500RL7 operate with different VDD and VDRIVE voltages?

Yes, the AD7352YRUZ-500RL7 supports independent VDD (2.25–2.75 V, nominal 2.5 V) and VDRIVE (2.25–3.6 V) supplies. This allows interfacing with 1.8 V, 2.5 V, or 3.3 V digital controllers while maintaining optimal analog performance-VDRIVE sets logic threshold levels without affecting ADC core operation.
