Product details
Overview
ADC101C027CIMKX/NOPB from Texas Instruments is a 10-bit I²C-compatible analog-to-digital converter in SOT-6 package, operating from +2.7V to +5.5V supply with 1 µs conversion time and ±0.5 LSB max INL/DNL. It features pin-selectable I²C address (three options), alert-free architecture (ADDR pin only), and automatic power-down mode consuming <1 µW idle. Used for real-time voltage monitoring in portable medical instruments and battery-powered test equipment.
For engineers reviewing the ADC101C027CIMKX/NOPB datasheet, ADC101C027CIMKX/NOPB pinout, ADC101C027CIMKX/NOPB application, or ADC101C027CIMKX/NOPB equivalent, key selection criteria include its SOT-6 footprint, single-address-selection input (ADDR), absence of ALERT output, guaranteed no missing codes, and support for I²C high-speed mode up to 3.4 MHz - critical for compact, low-power system monitoring designs.
Technical Context
The ADC101C027CIMKX/NOPB implements a successive-approximation register (SAR) ADC with internal track-and-hold and charge-redistribution DAC. Its analog input range is 0 V to VA, referenced to the same supply used for logic and conversion, eliminating need for external reference.
It operates exclusively in Normal Conversion Mode (no automatic conversion or alert interrupt), controlled via I²C interface supporting standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes. The ADDR pin sets one of three I²C slave addresses by tri-level logic (GND/VCC/float), enabling multi-device bus configuration without address conflicts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10 bits with no missing codes - ensures monotonic transfer function and deterministic digital output across full input range. |
| Conversion Time | 1 µs typical - enables maximum throughput of 188.9 kSPS at 3.4 MHz I²C clock, suitable for dynamic signal sampling. |
| INL / DNL | ±0.5 LSB max - guarantees linearity error under 0.05% of full scale, critical for precision measurement applications. |
| Supply Range | +2.7 V to +5.5 V - supports direct interfacing with 3.3 V and 5 V microcontrollers without level-shifting. |
| Power Consumption | 0.26 mW at 3 V / 22 kSPS - ultra-low active power enables >1-year battery life in coin-cell–powered sensors. |
| I²C Address Options | Three pin-selectable addresses (via ADDR tri-level input) - allows up to three ADC101C027 devices on same bus without address conflict. |
| ESD Protection | ±8 kV HBM on SDA/SCL pins - robust bus resilience for industrial and handheld equipment with frequent connector mating. |
Pinout & Package
SOT-6 package (2.2 mm × 1.35 mm, 0.95 mm height), lead-free and RoHS-compliant. Pin 1 marked with dot; pins are not internally connected to thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VA | Supply & Reference Input | Single-supply rail serving as both power source and analog reference; must be decoupled to GND with ≥0.1 µF ceramic capacitor. |
| 2 - GND | Analog & Digital Ground | Common return path for all internal circuitry; requires low-impedance connection to system ground plane. |
| 3 - VIN | Analog Input | Unbuffered input accepting 0 V to VA range; source impedance ≤100 Ω recommended for full AC performance. |
| 4 - ADDR | I²C Address Selection | Tri-level input (GND = 0x50, float = 0x51, VCC = 0x52) - selects one of three 7-bit slave addresses without external resistors. |
| 5 - SCL | I²C Clock Input | Open-drain input requiring external pull-up to VA; supports 100 kHz / 400 kHz / 3.4 MHz modes with 8 kV HBM ESD rating. |
| 6 - SDA | I²C Data I/O | Open-drain bidirectional data line; shares same ESD protection and pull-up requirement as SCL; handles ACK/NACK and register reads. |
Key Features
| Feature | Design Value |
|---|---|
| Successive Approximation Architecture | Enables deterministic 1 µs conversion latency and zero cycle latency between read and next conversion trigger. |
| Tri-Level ADDR Pin | Eliminates need for external address-setting resistors, reducing BOM count and PCB area in space-constrained designs. |
| Auto Power-Down Mode | Reduces quiescent current to ≤0.2 µA when I²C bus is idle - extends battery life without firmware intervention. |
| No Missing Codes Guarantee | Ensures monotonicity across full 10-bit range (0x000–0x3FF), preventing code skips that cause control-loop instability. |
| Industrial Temperature Range | −40°C to +105°C operation - validated for use in automotive cabin modules, industrial PLC I/O, and outdoor sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit I²C ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADC101C021CIMKX/NOPB | Includes ALERT output pin; no ADDR pin; same SOT-6 package and electrical specs. | Required where out-of-range interrupt signaling is needed (e.g., overvoltage detection in power supplies). | Select ADC101C021CIMKX/NOPB if system requires hardware alert assertion instead of software polling. |
| ADC121C027CIMKX/NOPB | 12-bit resolution; same SOT-6 package, ADDR pin, and I²C interface; higher power (0.35 mW at 3 V). | Used when ENOB > 10 bits is required (e.g., precision strain gauge readouts with <0.025% accuracy). | Choose ADC121C027CIMKX/NOPB only if 12-bit resolution is mandatory and additional 0.09 mW power budget is available. |
Compared with ADC101C021CIMKX/NOPB, the ADC101C027CIMKX/NOPB trades alert functionality for address configurability - enabling scalable multi-node sensing without interrupt lines.

FAQ
What is the I²C address configuration method for ADC101C027CIMKX/NOPB?
The ADC101C027CIMKX/NOPB uses a single tri-level ADDR pin to select one of three 7-bit I²C slave addresses: GND → 0x50, floating → 0x51, VCC → 0x52. This eliminates external address resistors and simplifies layout. No software address programming is required - the address is hardwired at power-on and remains fixed during operation of the ADC101C027CIMKX/NOPB.
Does ADC101C027CIMKX/NOPB support automatic conversion mode or alert interrupt functionality?
No. Unlike the ADC101C021 variant, the ADC101C027CIMKX/NOPB omits the ALERT pin and does not support automatic conversion mode or programmable alert limits. All conversions must be initiated explicitly via I²C read commands to the conversion result register. This makes the ADC101C027CIMKX/NOPB suitable for polled monitoring architectures where host MCU controls timing and threshold checking.
What is the maximum sampling rate achievable with ADC101C027CIMKX/NOPB?
The ADC101C027CIMKX/NOPB achieves a maximum throughput of 188.9 kSPS when operated with I²C high-speed mode at 3.4 MHz. At lower I²C speeds (400 kHz), the sustained rate drops to 22.2 kSPS. The 1 µs conversion time is fixed; actual sample rate depends on I²C bus overhead and host controller efficiency - the ADC101C027CIMKX/NOPB itself imposes no additional latency beyond conversion and register access.
Can ADC101C027CIMKX/NOPB operate from a 3.3 V supply while maintaining full 10-bit performance?
Yes. The ADC101C027CIMKX/NOPB is fully specified from +2.7 V to +5.5 V, including all AC and DC parameters. At 3.3 V, it delivers ±0.5 LSB max INL/DNL, 9.94-bit ENOB, and 61.6 dB SNR - meeting full 10-bit monotonicity and linearity specs. The LSB step size scales linearly with supply (3.3 V / 1024 ≈ 3.22 mV), preserving measurement resolution across the valid supply range of the ADC101C027CIMKX/NOPB.
What package type and mounting compatibility does ADC101C027CIMKX/NOPB use?
The ADC101C027CIMKX/NOPB is supplied in a 6-pin SOT-23 (SOT-6) package measuring 2.2 mm × 1.35 mm × 0.95 mm, with gull-wing leads and RoHS-compliant matte tin plating. It is compatible with standard reflow profiles (J-STD-020, peak 260°C), stencil-printed solder paste, and automated optical inspection. No thermal pad or exposed die attach is present - the package is fully surface-mountable using standard SMT processes for the ADC101C027CIMKX/NOPB.
