Product details
Overview
ADC101C021CIMM/NOPB from Texas Instruments is a 10-bit, I²C-compatible successive-approximation ADC operating from +2.7V to +5.5V supply, featuring an open-drain ALERT output, ±0.5 LSB max INL/DNL, 1 µs typical conversion time, and industrial temperature range (−40°C to +105°C). It serves as a system-monitoring sensor interface in portable medical instruments and battery-powered test equipment.
For engineers reviewing the ADC101C021CIMM/NOPB datasheet, ADC101C021CIMM/NOPB pinout, ADC101C021CIMM/NOPB application, or ADC101C021CIMM/NOPB equivalent, key selection criteria include its alert-triggered out-of-range detection, 188.9 kSPS maximum throughput, SOT-6 package footprint, I²C high-speed mode (3.4 MHz) support, and guaranteed no-missing-codes performance across full supply and temperature range.
Technical Context
The ADC101C021CIMM/NOPB implements a charge-redistribution DAC-based successive approximation architecture with internal track-and-hold, supporting analog input frequencies up to 11 MHz at +5.0V supply. Its ALERT function is driven by programmable upper/lower limit registers and operates independently of host polling.
It uses the VA supply as both power source and unbuffered reference, eliminating external reference components. The device supports three I²C speed modes-standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz)-with 8 kV HBM ESD protection on SDA/SCL pins for robust multi-board bus deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10 bits with guaranteed no missing codes - ensures monotonicity and deterministic code mapping for control-loop feedback. |
| Conversion Time | 1 µs typical - enables high-throughput sampling without CPU intervention in automatic mode. |
| INL / DNL | ±0.5 LSB maximum - maintains linearity critical for precision system monitoring and peak detection accuracy. |
| Throughput Rate | 188.9 kSPS maximum - supports real-time dynamic signal capture at 3.4 MHz I²C clock. |
| Supply Range | +2.7 V to +5.5 V - allows direct integration with 3.3 V and 5 V logic domains without level-shifting. |
| Power Consumption | 0.26 mW at 3 V / 22 kSPS - enables multi-year operation in coin-cell–powered portable instrumentation. |
| Alert Function | Dedicated open-drain ALERT output with programmable thresholds - provides hardware interrupt for out-of-range events without software polling. |
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; pin numbering follows standard SOT-6 convention (counterclockwise from mark).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VA | Power supply and unbuffered reference voltage - must be decoupled to GND with low-ESR capacitor for stable conversion accuracy. |
| 2 | GND | Analog/digital ground reference - shared return path for all internal circuitry; requires low-impedance PCB connection. |
| 3 | VIN | Analog input - accepts 0 V to VA range; input impedance dominated by 3 pF pin capacitance and 500 Ω switch RON. |
| 4 | ALERT | Open-drain digital output - asserts active-low when VIN exceeds programmed limits; requires external pull-up to VA. |
| 5 | SCL | I²C serial clock input - open-drain, 8 kV HBM ESD rated; must be pulled up externally; supports 3.4 MHz high-speed mode. |
| 6 | SDA | I²C bidirectional data line - open-drain, 8 kV HBM ESD rated; shares bus arbitration and ACK timing with SCL. |
Key Features
| Feature | Design Value |
|---|---|
| Alert-triggered interrupt | Hardware-level out-of-range detection with user-programmable high/low limits eliminates continuous host polling overhead. |
| Automatic conversion mode | Self-timed sampling at intervals set via Configuration Register (D7–D5) enables watchdog-style system monitoring without firmware scheduling. |
| Three-speed I²C interface | Native support for standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes simplifies integration into mixed-speed embedded buses. |
| Ultra-low power down | Sub-1 µW power consumption in PD1 mode (SCL/SDA held high) extends battery life during idle periods in portable devices. |
| Industrial temperature range | Guaranteed operation from −40°C to +105°C enables use in automotive cabin sensors and industrial PLC front-ends. |

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 |
|---|---|---|---|
| ADC101C027 | Replaces ALERT pin with ADDR pin for 3-level address selection; same resolution, timing, and power specs. | Preferred where multi-device I²C addressing is required instead of alert-driven interrupt signaling. | Select ADC101C027 when board layout includes address configuration resistors and no hardware interrupt line is available. |
| ADC121C021 | 12-bit resolution, identical SOT-6 package and pinout, higher INL (±1 LSB max), 1.2 µs conversion time. | Used when enhanced dynamic range (>72 dB SNR) is required for low-amplitude sensor signals. | Choose ADC121C021 only if system design mandates ≥12-bit ENOB and can accommodate 20% longer conversion latency. |
Compared with ADC101C027 and ADC121C021, the ADC101C021CIMM/NOPB uniquely balances alert-driven autonomy, 10-bit precision, and ultra-low quiescent power - making it optimal for resource-constrained, interrupt-sensitive monitoring roles where pin count and power budget are primary constraints.

FAQ
What is the maximum I²C clock frequency supported by the ADC101C021CIMM/NOPB?
The ADC101C021CIMM/NOPB supports I²C high-speed mode up to 3.4 MHz when bus capacitance is ≤100 pF. At 400 pF, maximum clock frequency drops to 1.7 MHz. Standard (100 kHz) and fast (400 kHz) modes are also fully supported. This flexibility allows the ADC101C021CIMM/NOPB to operate reliably across diverse embedded bus configurations without protocol translation.
Does the ADC101C021CIMM/NOPB require an external voltage reference?
No, the ADC101C021CIMM/NOPB uses its VA supply pin as both power source and unbuffered reference voltage. This eliminates the need for external reference components and reduces BOM count. However, VA must be low-noise and decoupled to GND with a ceramic capacitor to maintain specified INL and DNL performance.
How does the ALERT pin function in the ADC101C021CIMM/NOPB?
The ALERT pin on the ADC101C021CIMM/NOPB is an open-drain output that asserts low when the VIN input exceeds either the programmable upper or lower limit stored in the Alert Limit Registers. It remains asserted until the limit condition clears or the status is cleared via I²C read - enabling hardware-triggered interrupt handling without continuous polling of the ADC101C021CIMM/NOPB.
What is the guaranteed operating temperature range for the ADC101C021CIMM/NOPB?
The ADC101C021CIMM/NOPB is specified for continuous operation from −40°C to +105°C. All key parameters-including INL, DNL, conversion time, and power consumption-are guaranteed across this full industrial temperature range, making it suitable for under-hood automotive sensors and factory-floor industrial controllers.
Can the ADC101C021CIMM/NOPB operate from a 3.3 V supply?
Yes, the ADC101C021CIMM/NOPB operates over a supply range of +2.7 V to +5.5 V, fully supporting 3.3 V nominal systems. At 3.0 V and 22 kSPS, typical power consumption is 0.26 mW, and full-scale input range is 0 V to 3.0 V - enabling direct interfacing with 3.3 V microcontrollers and sensors without level shifters or regulators.
