Product details
Overview
ADS1113IRUGR from Texas Instruments is a 16-bit, delta-sigma analog-to-digital converter (ADC) with integrated voltage reference and oscillator, supporting single-ended or differential input configurations. It operates from 2.0V to 5.5V, consumes only 150μA in continuous-conversion mode, delivers up to 860 samples per second (SPS), and targets precision sensor measurement in space- and power-constrained systems such as battery monitoring and portable instrumentation.
For engineers reviewing the ADS1113IRUGR datasheet, ADS1113IRUGR pinout, ADS1113IRUGR application, or ADS1113IRUGR equivalent, key selection considerations include its fixed 1-channel I²C interface, absence of PGA/comparator, ultra-small X2QFN-10 (1.5mm × 2.0mm) package, and guaranteed operation from –40°C to +125°C - all critical for embedded industrial and automotive sensing nodes requiring minimal footprint and low quiescent current.
Technical Context
The ADS1113IRUGR implements a 1MHz internal oscillator divided to 250kHz modulator frequency, enabling delta-sigma conversion with single-cycle settling and programmable data rates from 8SPS to 860SPS. Its analog front-end uses switched-capacitor sampling with input impedance varying by full-scale range (e.g., ~6MΩ common-mode at ±2.048V FSR).
No PGA or digital comparator is integrated - unlike ADS1114/ADS1115 - making it a streamlined, cost-optimized variant for basic 1-channel differential or single-ended measurements where gain scaling or threshold alerting are handled externally.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit with no missing codes - ensures monotonicity and full dynamic range utilization in precision measurement. |
| Max Sample Rate | 860 SPS - supports real-time monitoring of slowly varying signals like temperature or battery voltage without oversampling burden. |
| Supply Voltage | 2.0V to 5.5V - enables direct interfacing with Li-ion batteries (2.7–4.2V), 3.3V microcontrollers, and 5V legacy systems without level-shifting. |
| Quiescent Current | 150 μA (continuous mode) - extends battery life in portable devices; drops to 0.5–2 μA in power-down state. |
| Input Configuration | 1 differential (AIN0–AIN1) or 1 single-ended (AIN0–GND) - simplifies signal routing for dedicated sensor channels. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, industrial control, and outdoor equipment environments. |
| I²C Address | 4 pin-selectable addresses (via ADDR pin) - allows up to four ADS1113IRUGR devices on same bus without address conflict. |
Pinout & Package
RUG package is a 10-pin, 1.5mm × 2.0mm, 0.4mm-thick X2QFN with wettable flanks - optimized for automated optical inspection (AOI) and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ADDR | Digital input | Selects one of four I²C slave addresses; pulled high/low or left floating to configure device address. |
| ALERT/RDY | Digital output | Open-drain ready flag - asserts low when conversion completes; not functional on ADS1113IRUGR (no comparator logic). |
| GND | Analog ground | Primary reference for analog inputs and internal reference; must be connected to system AGND with low-impedance path. |
| AIN0 | Analog input (+) | Positive input for differential measurement (vs AIN1) or single-ended measurement (vs GND). |
| AIN1 | Analog input (–) | Negative input for differential measurement; tied to GND externally for single-ended use. |
| VDD | Analog power supply | Supplies core ADC, reference, and oscillator; requires 0.1μF ceramic decoupling capacitor to GND. |
| SDA | I²C bidirectional data | Open-drain I²C data line; requires external pull-up to VDD (typically 2.2kΩ–10kΩ). |
| SCL | I²C clock input | Open-drain I²C clock line; requires external pull-up to VDD and supports Fast Mode (400kHz) timing. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated voltage reference | Low-drift internal reference eliminates need for external precision reference, reducing BOM count and layout area. |
| On-chip oscillator | 1MHz oscillator with 4× divider provides stable 250kHz modulator clock - removes external crystal or clock source dependency. |
| Single-cycle settling | Enables immediate read-after-convert in continuous mode, simplifying firmware timing and eliminating wait states. |
| Ultra-small X2QFN-10 | 1.5mm × 2.0mm footprint saves >60% board area vs comparable SOIC-8 or VSSOP-10 ADCs - ideal for wearables and compact modules. |
| I²C interface with address select | Four hardware-configurable slave addresses allow multiple ADS1113IRUGR units on one bus without software address remapping. |
Applications
| Battery Voltage Monitoring | Temperature Measurement Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit I²C ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS1114IRUGR | Includes PGA (±0.256V to ±6.144V gain ranges) and digital comparator; identical pinout and package. | Supports low-level sensor signals (e.g., mV-output load cells) and undervoltage/overvoltage alerts without external circuitry. | Select ADS1114IRUGR when signal conditioning or threshold detection is required; ADS1113IRUGR remains optimal for fixed-range, cost-sensitive designs. |
| ADS1013IRUGR | 12-bit resolution, 3300 SPS max, same package and I²C interface; lower power (150μA same, but faster conversion reduces active time). | Better suited for high-speed, lower-precision applications like audio pre-processing or basic voltage supervision. | Choose ADS1013IRUGR when 12-bit resolution suffices and higher throughput is prioritized over noise floor or DC accuracy. |
Compared with ADS1114IRUGR, ADS1113IRUGR trades PGA/comparator functionality for lower cost and simpler firmware, while ADS1013IRUGR offers higher speed at reduced resolution - making ADS1113IRUGR the balanced choice for precision, low-power, single-channel measurement where external gain or alert logic is already present.

FAQ
What is the maximum sample rate supported by the ADS1113IRUGR?
The ADS1113IRUGR supports a maximum sample rate of 860 samples per second (SPS). This rate is achievable across its full operating temperature range (–40°C to +125°C) and supply voltage range (2.0V to 5.5V), with timing compliance verified per I²C Fast Mode specifications. At lower data rates (e.g., 8SPS), the device achieves improved noise performance and effective resolution.
Does the ADS1113IRUGR include a programmable gain amplifier (PGA)?
No, the ADS1113IRUGR does not include a programmable gain amplifier. Unlike the ADS1114IRUGR and ADS1115IRUGR, this variant is optimized for fixed-gain, single-channel measurement. Its full-scale input voltage range is selectable only via external resistor dividers or direct connection - the internal PGA block is absent, confirmed in the Device Comparison Table and Functional Block Diagram.
What package type is used for the ADS1113IRUGR?
The ADS1113IRUGR uses the RUG package: a 10-pin, 1.5mm × 2.0mm, 0.4mm-thick X2QFN with wettable flanks. This package is explicitly designated in TI's orderable information and mechanical drawings, and differs from the DYN (SOT-10) and DGS (VSSOP-10) variants offered for other ADS111x members.
Can the ADS1113IRUGR operate from a 2.0V supply?
Yes, the ADS1113IRUGR is fully specified to operate from a minimum supply voltage of 2.0V up to 5.5V. Electrical characteristics including offset error, gain error, and noise performance are guaranteed across this entire range at temperatures from –40°C to +125°C, as documented in Section 5.3 (Recommended Operating Conditions) of the datasheet.
Is the ALERT/RDY pin functional on the ADS1113IRUGR?
No, the ALERT/RDY pin on the ADS1113IRUGR is not functional as a comparator output because the device lacks integrated comparator logic. Per the Pin Functions table and block diagram, this pin serves only as a conversion-ready indicator in ADS1114/ADS1115; on ADS1113IRUGR, it remains unconnected internally and should be left floating or pulled high via external resistor if unused.
