Product details
Overview
ADS7052IRUGR from Texas Instruments is a 14-bit, 1-MSPS successive-approximation register (SAR) analog-to-digital converter with single-ended input, 0 V to AVDD unipolar range, and integrated offset calibration. It operates from 1.65 V to 3.6 V AVDD/DVDD, supports –40°C to +125°C, and delivers 74.5-dB SINAD at 2 kHz for high-fidelity signal acquisition in compact sensor interfaces.
For engineers reviewing the ADS7052IRUGR datasheet, ADS7052IRUGR pinout, ADS7052IRUGR application, or ADS7052IRUGR equivalent, this page provides verified technical context, real-world design meaning of key specs, validated X2QFN-8 package mapping, confirmed SPI-compatible timing behavior, and two rigorously cross-checked alternative parts for optical encoder and sonar receiver designs.
Technical Context
The ADS7052IRUGR implements a true SAR architecture with internal CDAC and comparator, using AVDD as both analog supply and reference voltage. Its sampling stage employs dual 16-pF capacitors (CS1/CS2) and 50-Ω switch resistances (RS1/RS2), enabling precise single-ended acquisition with 230-ns acquisition time and 3-ns aperture delay.
It operates in three deterministic functional states-ACQ, CNV, and OFFCAL-controlled solely by CS and SCLK edges. Conversion requires exactly 18 SCLK falling edges per frame, with data output aligned to SCLK rising edges and tri-state control synchronized to CS transitions.

Pinout & Package
The ADS7052IRUGR is housed in an 8-pin X2QFN package measuring 1.5 mm × 1.5 mm × 0.35 mm, optimized for space-constrained PCB layouts and thermal performance (RθJA = 177.5°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: CS | Digital input | Active-low chip-select initiates conversion frame; falling edge triggers sampling and state transition from ACQ to CNV |
| 2: SDO | Digital output | Serial data output; tri-stated when CS is high; MSB-aligned to SCLK rising edge with 10-ns propagation delay |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 14-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7054IRUGR | Fully differential input architecture; identical 14-bit/1-MSPS spec but requires differential signal source and matched layout | Better CMRR and noise immunity in high-EMI motor drive or industrial bus environments | Select when sensor output is inherently differential or common-mode noise exceeds 20 mVpp |
| ADS7056IRUGR | 2.5-MSPS throughput; same 14-bit resolution and X2QFN-8 package; higher power (2.8 mW at 3.3 V) | Supports faster sampling for wideband I-Q demodulation or multi-tone spectral analysis | Select when system requires >1-MSPS sampling without sacrificing resolution or package size |
Compared with ADS7054IRUGR and ADS7056IRUGR, the ADS7052IRUGR provides optimal balance of resolution, power efficiency, and single-ended simplicity for cost-sensitive, space-constrained applications where 1-MSPS suffices and differential signaling is unnecessary.

FAQ
What is the maximum sampling rate supported by the ADS7052IRUGR?
The ADS7052IRUGR supports a maximum throughput rate of 1 MSPS, achieved with a 24-MHz SCLK and proper timing adherence (minimum 18 SCLK cycles per conversion). This rate is guaranteed across the full operating temperature range (–40°C to +125°C) and AVDD/DVDD supply range (1.65 V to 3.6 V), making it suitable for real-time acquisition of signals up to 200 kHz bandwidth.
Does the ADS7052IRUGR require an external voltage reference?
No, the ADS7052IRUGR uses AVDD as its internal reference voltage, eliminating the need for an external reference. The full-scale input range is 0 V to AVDD, and the device includes internal circuitry that switches AVDD to the CDAC during conversion. A 3.3-µF low-ESR ceramic capacitor between AVDD and GND is required to maintain reference stability during switching events.
How does the integrated offset calibration function in the ADS7052IRUGR?
The ADS7052IRUGR performs automatic offset calibration on power-up and optionally during normal operation in the OFFCAL state. This calibration maintains offset error within ±1 LSB across the entire AVDD range (1.65 V to 3.6 V) and temperature range (–40°C to +125°C), as verified in production testing. No external calibration command or host intervention is required for baseline operation.
What are the absolute maximum ratings for AVDD and DVDD on the ADS7052IRUGR?
The ADS7052IRUGR has absolute maximum ratings of –0.3 V to 3.9 V for both AVDD and DVDD relative to GND. Exceeding these limits may cause permanent damage. Recommended operating conditions specify AVDD and DVDD between 1.65 V and 3.6 V. These ratings are stress limits only and do not imply functional operation outside recommended conditions.
Can the ADS7052IRUGR interface directly with a 1.8-V microcontroller?
Yes, the ADS7052IRUGR supports DVDD from 1.65 V to 3.6 V and complies with JESD8-7A for DVDD = 1.65 V to 1.95 V, ensuring full interoperability with 1.8-V logic families. Digital inputs (CS, SCLK) accept 0.35×DVDD low and 0.65×DVDD high thresholds, while SDO outputs meet VOH/VOL specifications at 1.8 V, enabling direct connection without level shifters.
