Product details
Overview
ADS1110A0IDBVTG4 from Texas Instruments is a 16-bit delta-sigma analog-to-digital converter with integrated 2.048V reference, programmable gain amplifier (PGA), and I²C interface in SOT23-6 package. It delivers ±0.01% FSR INL, 15–240 SPS programmable data rate, and 240 µA active current consumption. It enables high-resolution differential voltage measurement in space-constrained portable instrumentation.
For engineers reviewing the ADS1110A0IDBVTG4 datasheet, ADS1110A0IDBVTG4 pinout, ADS1110A0IDBVTG4 application, or ADS1110A0IDBVTG4 equivalent, key selection considerations include its fixed I²C address (1001000), onboard self-calibration, differential input range of ±2.048V/PGA, and single-supply operation from 2.7V to 5.5V.
Technical Context
The ADS1110A0IDBVTG4 implements a fully differential, continuously self-calibrating delta-sigma modulator with integrated digital filter and 2.048V reference. Its switched-capacitor input stage provides differential impedance of 2.8 MΩ/PGA and common-mode impedance dependent on PGA setting (e.g., 3.5 MΩ at PGA=1).
It operates exclusively in I²C slave mode with no external clock support, using an internal oscillator nominally at 275 kHz. Conversion modes include continuous or single-cycle, with automatic power-down after conversion in single mode-reducing idle current to 0.05 µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit (no missing codes at 15 SPS); resolution scales with data rate (12–16 bits) |
| INL | ±0.01% of FSR max - ensures accurate end-point linearity for precision sensor digitization |
| Data Rate | 15 / 30 / 60 / 240 SPS - selectable via configuration register; trade-off between speed and effective resolution |
| PGA Gain | 1, 2, 4, or 8 - extends usable input range down to ±256 mV full-scale at PGA=8 |
| Reference | 2.048 V ±0.05%, 5 ppm/°C drift - internal only; defines absolute input range and contributes to total gain error |
| Supply Range | 2.7 V to 5.5 V - supports direct interfacing with 3.3 V and 5 V microcontrollers without level-shifting |
| I²C Address | 1001000 (0x48) - fixed factory-set address; enables up to eight ADS1110 variants on one bus |
Pinout & Package
SOT23-6 package (DBV), 2.9 mm × 1.6 mm × 1.15 mm body, gull-wing leads, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply input | Accepts 2.7–5.5 V; powers all internal blocks including reference, modulator, and I²C interface |
| GND | Ground reference | Common return for analog and digital circuits; must be low-impedance to minimize offset drift |
| SDA | I²C data line | Open-drain bidirectional interface; requires external pull-up resistor (typically 2.2–10 kΩ) |
| SCL | I²C clock input | Input-only; driven by master; supports Standard (100 kHz), Fast (400 kHz), and High-Speed (3.4 MHz) modes |
| VIN+ | Differential positive input | Accepts voltage up to VDD + 0.3 V; used with VIN− for true differential measurement |
| VIN− | Differential negative input | Accepts voltage down to GND − 0.2 V; input pair defines full-scale range as ±2.048 V / PGA |
Key Features
| Feature | Design Value |
|---|---|
| Onboard 2.048 V reference | Eliminates need for external precision reference; ±0.05% initial accuracy reduces BOM count and layout area |
| Programmable gain amplifier (PGA) | Configurable gain (1–8) enables high-resolution measurement of small signals (e.g., thermocouple or bridge outputs) without external amplification |
| Continuous self-calibration | Automatically corrects offset and gain errors in real time; no user intervention or calibration registers required |
| Single-cycle conversion mode | Reduces average current to <1 µA in battery-powered applications by powering down immediately after conversion completion |
| Differential input architecture | Rejects common-mode noise up to 105 dB at DC (PGA=8); improves immunity in noisy industrial environments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision delta-sigma ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP3421-E/P | 18-bit resolution, 3.75 SPS min, no onboard reference (requires external 2.048 V), 6-pin DIP package | Higher resolution but slower; lacks integrated reference and PGA - demands external components for same functionality | Select when ultra-high resolution at low speed is prioritized over integration and board space |
| ADS1015IDGSR | 12-bit resolution, 3300 SPS max, 4-channel input, same 2.048 V reference and I²C interface (address 0x48) | Higher speed and channel count but lower resolution; shares pinout compatibility only in QFN package (not SOT23) | Select when multi-channel scanning or faster sampling is needed, accepting reduced precision per channel |
Compared with MCP3421-E/P and ADS1015IDGSR, the ADS1110A0IDBVTG4 uniquely combines 16-bit resolution, onboard reference, PGA, and SOT23-6 footprint - delivering highest integration density for single-channel, battery-sensitive precision measurement.

FAQ
What is the I²C address of the ADS1110A0IDBVTG4?
The ADS1110A0IDBVTG4 has a fixed 7-bit I²C address of 1001000 (0x48), set at the factory and unchangeable. This allows up to eight ADS1110 variants (A0–A7) to coexist on the same I²C bus without address conflict. The ADS1110A0IDBVTG4 does not support address pins or software-configurable addressing.
Does the ADS1110A0IDBVTG4 require an external reference voltage?
No, the ADS1110A0IDBVTG4 integrates a precision 2.048 V reference with ±0.05% initial accuracy and 5 ppm/°C drift. This reference is internal-only and cannot be bypassed, measured externally, or replaced. All gain and INL specifications include its contribution, eliminating need for external reference components.
Can the ADS1110A0IDBVTG4 measure single-ended signals?
No, the ADS1110A0IDBVTG4 supports only fully differential input (VIN+ and VIN−). It does not provide a dedicated ground-referenced input mode. To digitize single-ended sources, external circuitry such as an instrumentation amplifier configured for differential output is required before connecting to the ADS1110A0IDBVTG4 inputs.
What is the maximum input voltage range for the ADS1110A0IDBVTG4?
The ADS1110A0IDBVTG4 accepts differential input voltages up to ±2.048 V / PGA. With PGA = 1, full-scale range is ±2.048 V; with PGA = 8, it is ±256 mV. Absolute input limits are GND − 0.2 V ≤ VIN−, VIN+ ≤ VDD + 0.3 V - exceeding these risks damage or invalid conversion results.
How does the ADS1110A0IDBVTG4 handle power management in battery-powered systems?
The ADS1110A0IDBVTG4 supports single-conversion mode where it powers down automatically after each conversion, reducing quiescent current to 0.05 µA. In active conversion, it draws only 240 µA typical - enabling multi-year operation from coin-cell batteries in intermittent-sampling applications like wireless sensor nodes.
