Product details
Overview
ADS1013IDGSR from Texas Instruments is a 12-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 3.3kSPS, and targets space- and power-constrained sensor measurement systems such as battery monitoring.
For engineers reviewing the ADS1013IDGSR datasheet, ADS1013IDGSR pinout, ADS1013IDGSR application, or ADS1013IDGSR equivalent, key selection criteria include its fixed ±2.048V full-scale range, absence of PGA/comparator, I²C interface with four selectable addresses, and X2QFN-10 (RUG) ultra-small package for high-density PCB layouts.
Technical Context
The ADS1013IDGSR implements a delta-sigma ADC core with internal 1MHz oscillator (divided to 250kHz modulator frequency), fixed ±2.048V full-scale range, and no programmable gain amplifier or digital comparator. Its analog input stage presents ~6MΩ common-mode and ~4.9MΩ differential input impedance at this FSR, enabling direct connection to low-impedance sensors without buffering in many cases.
It supports two conversion modes: single-shot (for ultra-low-power periodic sampling) and continuous-conversion (with programmable data rates from 128SPS to 3300SPS). Conversion settles in one cycle - e.g., 303μs at 3.3kSPS - and outputs 12-bit codes with guaranteed no missing codes across –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - ensures monotonicity and predictable code transitions in closed-loop control or threshold detection. |
| Max Sample Rate | 3.3kSPS - supports real-time monitoring of fast-changing signals like motor current transients or audio envelope detection. |
| Supply Range | 2.0V to 5.5V - enables direct operation from Li-ion batteries (3.0–4.2V), 3.3V logic rails, or 5V industrial supplies without LDO. |
| Quiescent Current | 150μA in continuous mode - extends battery life in portable instrumentation; drops to 0.5–2μA in power-down state. |
| Input Configuration | 1 differential (AIN0–AIN1) or 1 single-ended (AIN0–GND) - simplifies signal routing with minimal external components. |
| Reference & Clock | Internal low-drift voltage reference and 1MHz oscillator - eliminates need for external precision reference or crystal, reducing BOM count and board area. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, industrial motor drives, and factory automation environments. |
Pinout & Package
X2QFN-10 (RUG) package: 1.5mm × 2mm × 0.4mm, leadless, wettable flank, thermal pad on bottom. Requires controlled-impedance layout and proper thermal via stitching for reliable solder joint formation and thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ADDR | I²C address select | Digital input that sets one of four I²C slave addresses (0x48–0x4B); pulled high/low externally to configure bus topology. |
| ALERT/RDY | Open-drain status output | Not functional on ADS1013IDGSR - must be left unconnected or tied to VDD via pullup; unused in this variant. |
| GND | Analog ground | Primary return path for analog inputs and internal reference; requires low-impedance connection to system AGND plane. |
| AIN0 | Positive analog input | Accepts single-ended voltage (vs GND) or differential positive input (vs AIN1); max input = VDD + 0.3V per absolute ratings. |
| AIN1 | Negative analog input | Used only in differential mode (AIN0–AIN1); for single-ended use, connect externally to GND - not internally switched. |
| VDD | Power supply | Supplies analog and digital circuitry; requires 0.1μF ceramic decoupling capacitor placed ≤2mm from pin. |
| SDA | I²C bidirectional data | Open-drain I/O requiring external pullup to VDD; supports standard/fast-mode I²C up to 400kHz. |
| SCL | I²C clock input | Open-drain input requiring external pullup to VDD; timing compliant with JEDEC Std 47.1 for robust noise immunity. |
| NC (Pins 2,6,7) | No-connect | Internally unconnected; leave floating or tie to GND per TI layout guidelines to minimize parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small X2QFN-10 footprint | 1.5mm × 2mm area saves >60% board space vs SOIC-8 ADCs - critical for wearables and compact IoT nodes. |
| Single-cycle settling | Conversion time = 1/data rate (e.g., 303μs @ 3.3kSPS) - enables deterministic timing in time-critical firmware loops. |
| Integrated oscillator & reference | Eliminates external clock source and reference IC - reduces component count, cost, and calibration complexity. |
| Wide 2.0–5.5V supply range | Operates directly from primary battery cells or mixed-voltage domains without level-shifting or regulation overhead. |
| –40°C to +125°C operation | Validated performance across full automotive and industrial temperature ranges - no derating required. |
Applications
| Battery Voltage Monitoring | Temperature Measurement Systems |
|---|---|
Use Scenario: Real-time tracking of Li-ion cell voltage during charge/discharge cycles in portable medical devices.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit, I²C ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS1014IDGSR | Includes PGA (±0.256V to ±6.144V FSR) and digital comparator; same pinout and package. | Enables direct measurement of mV-level sensor outputs (e.g., load cells) and hardware overvoltage alerts. | Select when signal conditioning or threshold-triggered interrupts are required - adds no layout change but increases firmware complexity. |
| MCP3221A0T-E/OT | 12-bit SAR ADC, 188kSPS max, no internal reference or oscillator; requires external clock and reference. | Higher speed but lacks integrated timing/reference - demands additional components and calibration effort. | Prefer for high-throughput, low-latency sampling where external reference stability is already managed elsewhere in design. |
Compared with ADS1014IDGSR, ADS1013IDGSR offers lower system cost and simpler firmware but sacrifices signal flexibility; versus MCP3221A0T-E/OT, it trades raw speed for integration, reducing bill-of-materials and qualification effort in battery-powered edge nodes.

FAQ
What is the full-scale input range of the ADS1013IDGSR?
The ADS1013IDGSR has a fixed full-scale range of ±2.048V for differential inputs (AIN0–AIN1) or single-ended inputs (AIN0–GND). This value is not programmable - unlike ADS1014/ADS1015 - and is set by internal design. The corresponding LSB size is exactly 1mV (2.048V ÷ 2¹²), enabling straightforward voltage-to-code conversion without gain calibration.
Does the ADS1013IDGSR include a programmable gain amplifier (PGA)?
No, the ADS1013IDGSR does not include a programmable gain amplifier. This distinguishes it from the ADS1014IDGSR and ADS1015IDGSR, which integrate PGA and digital comparators. The ADS1013IDGSR provides only the core 12-bit delta-sigma ADC, internal reference, and oscillator - making it the most minimal, lowest-cost variant in the ADS101x family.
Can the ALERT/RDY pin on the ADS1013IDGSR be used for conversion-ready signaling?
No, the ALERT/RDY pin is not functional on the ADS1013IDGSR. It is reserved for comparator output or conversion-ready indication in ADS1014/ADS1015 variants only. On ADS1013IDGSR, this pin must be left unconnected or tied to VDD with a pullup resistor - it serves no active role and does not assert during conversions.
What package type is used for the ADS1013IDGSR?
The ADS1013IDGSR uses the RUG package: a 10-pin X2QFN measuring 1.5mm × 2mm × 0.4mm with an exposed thermal pad. This ultra-compact, leadless package supports automated optical inspection (AOI) and offers superior thermal performance vs. SOT-10 or VSSOP-10 variants - ideal for high-density PCBs in portable electronics.
How does the ADS1013IDGSR handle I²C address selection?
The ADS1013IDGSR supports four I²C slave addresses (0x48–0x4B) selected via the ADDR pin: grounded (0x48), tied to VDD (0x49), connected to SDA (0x4A), or connected to SCL (0x4B). This enables up to four ADS1013IDGSR devices on the same I²C bus without address conflict - essential for multi-channel sensor arrays in compact designs.
