Product details
Overview
ADS1113BQDGSRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified, 16-bit delta-sigma ADC with integrated voltage reference and oscillator, supporting 1 differential or 1 single-ended input, 8–860 SPS data rate, and I²C interface with four pin-selectable addresses. It operates from 2.0 V to 5.5 V and draws only 150 µA in continuous-conversion mode, enabling precise low-power sensor monitoring in space-constrained automotive displays.
For engineers reviewing the ADS1113BQDGSRQ1 datasheet, ADS1113BQDGSRQ1 pinout, ADS1113BQDGSRQ1 application, or ADS1113BQDGSRQ1 equivalent, key selection criteria include its lack of PGA/comparator (vs. ADS1114-Q1/ADS1115-Q1), fixed 1-channel configuration, VSSOP-10 package, automotive temperature range (–40°C to +125°C), and functional safety documentation support.
Technical Context
The ADS1113BQDGSRQ1 implements a delta-sigma modulation architecture with internal 2.048-V low-drift voltage reference and on-chip oscillator-eliminating external timing components. Its conversion core accepts only one differential pair (AIN0–AIN1) or one single-ended input (AIN0–GND), with no programmable gain amplifier or digital comparator.
It uses a 16-bit sigma-delta ADC core delivering single-cycle settling and supports eight programmable data rates (8–860 SPS). The I²C interface operates in standard/fast/high-speed modes up to 3.4 MHz and features four hardware-addressable target addresses via the ADDR pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees monotonic output and no missing codes across full operating range. |
| Data Rate | 8–860 SPS - selectable via config register; lower rates improve noise performance (e.g., 8 SPS yields 7.81 µVRMS at ±0.256 V FSR). |
| Supply Range | 2.0 V to 5.5 V - enables direct interface with 3.3-V and 5-V automotive microcontrollers without level-shifting. |
| Quiescent Current | 150 µA (continuous) - allows always-on sensing in battery-sensitive modules like camera control units. |
| Input Configuration | 1 differential (AIN0–AIN1) or 1 single-ended (AIN0–GND) - fixed channel count; no MUX or PGA. |
| Reference | Internal 2.048-V low-drift reference - eliminates need for external precision reference and reduces BOM count. |
| Temperature Grade | AEC-Q100 Grade 1 (–40°C to +125°C) - qualified for under-hood and instrument cluster mounting locations. |
Pinout & Package
ADS1113BQDGSRQ1 is packaged in a 10-pin VSSOP (DGS) with 3.00 mm × 3.00 mm body size and 0.5-mm lead pitch. This thermally enhanced, surface-mount package supports automated assembly and meets automotive reflow profiles.
| 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 to configure bus addressing. |
| GND | Analog ground | Primary return path for analog inputs and reference; must be connected to system AGND plane with low-impedance trace. |
| AIN0 | Positive analog input | Accepts single-ended input (vs. GND) or positive leg of differential pair (with AIN1 as negative leg). |
| AIN1 | Negative analog input | Used only in differential mode with AIN0; left unconnected in single-ended operation. |
| VDD | Power supply | Supplies both analog and digital circuitry; requires local 0.1-µF ceramic decoupling capacitor to GND. |
| SCL | I²C clock input | Open-drain compatible; requires external pullup to VDD (typically 4.7 kΩ) for proper bus timing. |
| SDA | I²C bidirectional data | Open-drain I/O; shares same pullup as SCL; supports multi-master arbitration and clock stretching. |
Key Features
| Feature | Design Value |
|---|---|
| Delta-sigma architecture | Delivers inherent 50/60-Hz rejection and high common-mode rejection (105 dB at DC, 105 dB at 60 Hz) without external filtering. |
| Integrated oscillator | Removes need for external crystal or clock source-reducing component count, board area, and startup delay. |
| Internal voltage reference | 2.048-V low-drift reference (±5 ppm/°C typical) ensures stable full-scale accuracy across temperature without calibration. |
| AEC-Q100 Grade 1 qualification | Validated for automotive ambient temperatures (–40°C to +125°C) and ESD robustness (HBM ±2000 V, CDM ±750 V on corner pins). |
| I²C interface with 4 addresses | Enables up to four ADS1113BQDGSRQ1 devices on same bus without address conflict-ideal for multi-sensor clusters. |

FAQ
What is the maximum sample rate of the ADS1113BQDGSRQ1?
The ADS1113BQDGSRQ1 supports a maximum data rate of 860 samples per second (SPS) in continuous-conversion mode. This rate is programmable via the configuration register and applies across the full operating temperature range (–40°C to +125°C). At 860 SPS, the device maintains 16-bit resolution with typical RMS noise of 7.81 µV at ±0.256-V full-scale range. Lower data rates (e.g., 8 SPS) reduce noise further but increase conversion time.
Does the ADS1113BQDGSRQ1 include a programmable gain amplifier (PGA)?
No, the ADS1113BQDGSRQ1 does not include a programmable gain amplifier. Unlike the ADS1114BQDGSRQ1 and ADS1115BQDGSRQ1 variants, the ADS1113BQDGSRQ1 is optimized for direct connection of medium-to-large amplitude signals (±0.256 V to ±6.144 V full-scale range) without amplification. Its input stage is fixed-gain, simplifying design and reducing quiescent current to 150 µA.
Which package options are available for the ADS1113BQDGSRQ1?
The ADS1113BQDGSRQ1 is offered exclusively in the 10-pin VSSOP (DGS) package, measuring 3.00 mm × 3.00 mm with 0.5-mm lead pitch. While the broader ADS111x-Q1 family also includes a UQFN-10 (NKS) variant, the ADS1113BQDGSRQ1 part number specifically corresponds to the VSSOP-10 package per TI's official orderable information and datasheet package addendum.
What I²C addresses does the ADS1113BQDGSRQ1 support?
The ADS1113BQDGSRQ1 supports four I²C slave addresses: 0x48, 0x49, 0x4A, and 0x4B. Address selection is controlled by the logic level applied to the ADDR pin (pin 1): grounded for 0x48, tied to VDD for 0x49, connected to SDA for 0x4A, and connected to SCL for 0x4B. This enables up to four ADS1113BQDGSRQ1 devices on the same I²C bus without address conflict.
Is the ADS1113BQDGSRQ1 qualified for automotive applications?
Yes, the ADS1113BQDGSRQ1 is AEC-Q100 qualified for automotive use (Grade 1: –40°C to +125°C ambient temperature). It meets stringent automotive reliability standards including HBM ESD classification level 2 (±2000 V) and CDM level C4B (±750 V on corner pins).
