Product details
Overview
ADC081C027CIMKX/NOPB from Texas Instruments is an 8-bit I²C-compatible successive-approximation ADC in SOT-6 package, operating from +2.7V to +5.5V supply with 1 µs typical conversion time, ±0.2 LSB max INL/DNL, and integrated address selection (ADDR) pin for three configurable slave addresses. It delivers 188.9 ksps maximum throughput and supports I²C high-speed mode (3.4 MHz) for real-time system monitoring in portable instrumentation.
For engineers reviewing the ADC081C027CIMKX/NOPB datasheet, ADC081C027CIMKX/NOPB pinout, ADC081C027CIMKX/NOPB application, or ADC081C027CIMKX/NOPB equivalent, key selection criteria include its SOT-6 footprint with ADDR-only interface (no ALERT), 3-pin-selectable I²C address capability, 8kV HBM ESD protection on SDA/SCL, automatic power-down (<1 µW), and guaranteed no missing codes across −40°C to +105°C.
Technical Context
The ADC081C027CIMKX/NOPB implements a charge-redistribution DAC architecture with internal track-and-hold, enabling full-scale input bandwidth up to 11 MHz at 5.0 V supply. Its analog input range is strictly 0 V to VA, referenced to the same supply used for digital logic and I²C interface.
It operates exclusively in Normal and Automatic Conversion modes via I²C register control, with dedicated Configuration, Alert Limit, Lowest/ Highest Conversion, and Pointer registers. Unlike the ADC081C021, it lacks an ALERT output but includes a tri-level ADDR pin that sets bits A0–A1 of the 7-bit slave address - enabling three distinct I²C addresses on a shared bus without external hardware.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8 bits with no missing codes - ensures monotonicity and deterministic code transitions across full temperature range. |
| Conversion Time | 1 µs typical - enables sampling at up to 188.9 ksps, suitable for fast transient detection in battery-powered systems. |
| INL / DNL | ±0.2 LSB max - guarantees linearity error ≤0.08% FS, critical for precision threshold monitoring and calibration. |
| Supply Range | +2.7 V to +5.5 V - allows direct interfacing with 3.3 V or 5 V microcontrollers without level-shifting. |
| I²C Speed Modes | Standard (100 kHz), Fast (400 kHz), High-Speed (3.4 MHz) - supports scalable bus loading and low-latency polling in dense sensor networks. |
| Power Consumption | 0.26 mW at 3 V / 22 ksps - enables multi-year operation in coin-cell–powered devices with minimal thermal impact. |
| ESD Protection | ±8 kV HBM on SDA/SCL - eliminates need for external TVS diodes in board-level ESD design for industrial environments. |
Pinout & Package
SOT-6 package (DDC), 2.2 mm × 1.35 mm × 0.95 mm body, moisture sensitivity level 1 (MSL-1), lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Analog Input | Single-ended input referenced to GND; accepts 0 V to VA range; requires <100 Ω source impedance for full performance. |
| GND | Ground | Common reference for analog and digital circuitry; must be low-impedance connection to minimize noise coupling. |
| VA | Supply & Reference | Single supply powers core and serves as unbuffered ADC reference; must be decoupled with ≥0.1 µF ceramic capacitor. |
| SDA | I²C Bidirectional Data | Open-drain interface requiring external pull-up to VA; 8 kV HBM ESD rating enables multi-board I²C routing. |
| SCL | I²C Clock Input | Open-drain clock input with same ESD robustness as SDA; timing supports 3.4 MHz high-speed mode under 100 pF load. |
| ADDR | Address Selection | Tri-level input setting A0/A1 bits; logic low/mid/high selects one of three I²C slave addresses (0x50, 0x51, 0x52). |
Key Features
| Feature | Design Value |
|---|---|
| Three-pin-selectable I²C addresses | Enables up to three ADC081C027CIMKX/NOPB units on one I²C bus without address conflict or external jumpers. |
| Automatic power-down mode | Reduces supply current to ≤0.2 µA when idle - extends battery life in intermittent-sampling applications like wearable sensors. |
| No missing codes over full temperature range | Guarantees monotonic transfer function from −40°C to +105°C, eliminating risk of code skipping in safety-critical monitoring. |
| High-speed I²C support (3.4 MHz) | Permits sub-10 µs register reads, enabling tight control loops in closed-loop power management or motor feedback systems. |
| Integrated track-and-hold with 11 MHz full-power bandwidth | Supports accurate digitization of fast-rising signals (e.g., overvoltage transients) without external sample-hold circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit I²C ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADC081C021CIMKX/NOPB | SOT-6 package with ALERT output instead of ADDR; supports out-of-range interrupt signaling but only one fixed I²C address (0x50). | Preferred where hardware interrupt-driven response to voltage excursions is required, e.g., overvoltage lockout circuits. | Select ADC081C021CIMKX/NOPB when alert-driven firmware actions are needed; ADC081C027CIMKX/NOPB when multi-device I²C addressing is prioritized. |
| ADC101C027CIMKX/NOPB | 10-bit resolution, same SOT-6 package and ADDR pin; identical I²C interface, timing, and power specs; higher ENOB (9.2 bits vs. 7.8). | Suitable for applications needing finer quantization (e.g., precision thermistor readout), but increases data volume and processing overhead. | Choose ADC101C027CIMKX/NOPB if 10-bit resolution is mandatory and system bandwidth permits larger I²C payloads; retain ADC081C027CIMKX/NOPB for cost- and power-sensitive 8-bit use cases. |
Compared with ADC081C021CIMKX/NOPB, ADC081C027CIMKX/NOPB trades interrupt capability for flexible I²C addressing - enabling scalable sensor node deployment. Against ADC101C027CIMKX/NOPB, it offers lower power and simpler firmware integration at the expense of 2-bit resolution, making it optimal for threshold-based monitoring rather than high-fidelity waveform capture.

FAQ
What is the I²C address configuration method for ADC081C027CIMKX/NOPB?
The ADC081C027CIMKX/NOPB uses a tri-level ADDR pin to select one of three I²C slave addresses: logic low = 0x50, mid-level = 0x51, high = 0x52. This eliminates external address resistors and allows up to three ADC081C027CIMKX/NOPB devices on a single I²C bus without conflict. The ADDR pin voltage thresholds are defined relative to VA, not fixed logic levels.
Does ADC081C027CIMKX/NOPB support alert or interrupt functionality?
No, ADC081C027CIMKX/NOPB does not include an ALERT output pin. That function is exclusive to the ADC081C021 variant. The ADC081C027CIMKX/NOPB relies entirely on polled I²C reads for conversion result retrieval and limit checking - firmware must periodically query the Highest/Lowest Conversion Registers to detect out-of-range conditions.
What is the maximum analog input frequency supported by ADC081C027CIMKX/NOPB?
The ADC081C027CIMKX/NOPB has a full-power bandwidth of 11 MHz at 5.0 V supply, meaning it can accurately digitize input signals up to that frequency before amplitude drops by 3 dB. However, effective dynamic performance (e.g., SINAD ≥49 dB) is specified at 1 kHz input; for higher frequencies, anti-aliasing filtering and low-impedance drive (<100 Ω) are essential to maintain ADC081C027CIMKX/NOPB's rated linearity and noise performance.
Can ADC081C027CIMKX/NOPB operate from a 3.3 V supply while maintaining full specifications?
Yes, ADC081C027CIMKX/NOPB is fully specified from +2.7 V to +5.5 V. At 3.3 V, it maintains all key parameters: ±0.2 LSB max INL/DNL, 1 µs conversion time, 188.9 ksps throughput in high-speed I²C mode, and −40°C to +105°C operation. Power consumption drops to 0.26 mW at 22 ksps, making it ideal for 3.3 V microcontroller systems with strict energy budgets.
Is ADC081C027CIMKX/NOPB pin-compatible with other members of the ADC081Cxx family?
Yes, ADC081C027CIMKX/NOPB shares identical SOT-6 pinout and footprint with ADC081C021CIMKX/NOPB and ADC101C027CIMKX/NOPB. Pin-for-pin compatibility extends to electrical behavior and register map - only the ADDR/ALERT pin assignment differs between variants. This allows drop-in replacement during design iteration or cost optimization without PCB revision.
