Product details
Overview
AD7416ARMZ-REEL from Analog Devices is a dedicated 10-bit digital temperature sensor IC with I²C interface, −40°C to +125°C measurement range, ±2°C accuracy (−25°C to +100°C), and open-drain overtemperature indicator (OTI) output - used for ambient thermal monitoring in battery-powered and space-constrained systems.
For engineers reviewing the AD7416ARMZ-REEL datasheet, AD7416ARMZ-REEL pinout, AD7416ARMZ-REEL application, or AD7416ARMZ-REEL equivalent, key selection criteria include its single-function thermal sensing role, 8-pin MSOP package, I²C address programmability (A0–A2), automatic power-down (0.2–1.5 µA shutdown current), and OTI fault queue configuration for noise-immune thermal alerts.
Technical Context
The AD7416ARMZ-REEL integrates a bandgap-based temperature sensor, 10-bit successive approximation ADC, on-chip oscillator, and I²C serial interface - all operating from a single 2.7 V to 5.5 V supply. It lacks external analog inputs (unlike AD7417/AD7418), dedicating Channel 0 exclusively to temperature conversion.
Its OTI output is open-drain, configurable as comparator or interrupt mode via the configuration register, with a programmable fault queue counter (1–4 consecutive out-of-limit readings) to suppress false triggers. Temperature data is read from the 16-bit Temperature Value Register after a 40 µs conversion.
Key Specifications

| Temperature Range | −40°C to +125°C operating range; supports industrial and automotive ambient monitoring |
| Accuracy | ±2.0°C at −25°C to +100°C; ±3.0°C across full range - enables reliable thermal thresholding |
| Resolution | 10-bit (0.25°C/LSB); delivers fine-grained thermal feedback without external signal conditioning |
| Conversion Time | 40 µs per temperature reading - supports up to ~2.5 kSPS thermal sampling |
| Supply Current | 350–600 µA active (I²C inactive); 0.2–1.5 µA shutdown - extends battery life in portable devices |
| I²C Address Pins | A0, A1, A2 support 8-device bus addressing - simplifies multi-sensor thermal mapping |
| OTI Output | Open-drain, programmable polarity and fault queue - allows robust overtemperature signaling without external logic |
Pinout & Package
AD7416ARMZ-REEL is housed in an 8-lead MSOP (Mini Small Outline Package) with 0.65 mm pitch, 3 mm × 3 mm body, and exposed pad for thermal enhancement. Pin 1 is SDA; pin 8 is VDD. The package is RoHS-compliant and moisture-sensitive level 1 (MSL-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SDA) | I²C bidirectional data line | Push-pull output; connects directly to microcontroller I²C bus without pull-up dependency on device side |
| 2 (SCL) | I²C clock input | Accepts standard I²C clock rates up to 400 kHz; timing compliant per Figure 4 (t1 = 2.5 µs min) |
| 3 (OTI) | Overtemperature indicator output | Open-drain logic output; requires external pull-up; asserts when temp > TOTI register value |
| 4 (GND) | Analog/digital ground reference | Single ground plane required; ties track-and-hold, comparator, and digital logic to common 0 V |
| 5 (A2) | I²C address MSB input | Logic high/low sets bit 2 of 7-bit slave address (base 0x90); enables up to 8 devices on one bus |
| 6 (A1) | I²C address middle bit input | Logic high/low sets bit 1 of slave address; combined with A0/A2 for full 3-bit address selection |
| 7 (A0) | I²C address LSB input | Logic high/low sets bit 0 of slave address; determines unique I²C address within group |
| 8 (VDD) | Positive supply rail | 2.7 V to 5.5 V operation; powers internal oscillator, ADC, and I²C interface; decoupling cap required |
Key Features
| Feature | Design Value |
|---|---|
| Dedicated temperature sensing only | No external analog inputs - eliminates channel crosstalk, simplifies layout, and reduces BOM count vs. multi-channel ADCs |
| Programmable OTI fault queue | Configurable 1–4 consecutive out-of-limit readings required before OTI assertion - prevents spurious alarms in electrically noisy environments |
| Auto power-down after conversion | Enters low-power state automatically post-read; reduces average current in polling-based thermal monitoring |
| On-chip 2.5 V reference | Internal reference used for ADC; eliminates need for external precision reference unless higher accuracy is required |
| I²C-compatible serial interface | Fully compliant with standard-mode (100 kHz) and fast-mode (400 kHz) I²C protocols - interoperable with most microcontrollers |
| Default thermal thresholds | TOTI = 80°C and THYST = 75°C at power-on - provides immediate overtemperature protection without register initialization |

Equivalent & Alternatives
The following parts are listed as comparable options for similar temperature monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM75BIMM-3/NOPB | 9-bit resolution; ±2°C accuracy; no programmable fault queue; fixed 7-bit I²C address (0x48) | Lacks OTI hysteresis and queue filtering - more susceptible to noise-induced false trips | Choose for cost-sensitive, non-critical thermal alerts where 0.5°C coarser resolution is acceptable |
| MAX31820MUA+ | 1-Wire interface; ±0.5°C accuracy; parasitic power capable; 12-bit resolution | Requires single-wire bus instead of I²C; supports longer trace runs but adds protocol overhead | Prefer for distributed sensor networks with long interconnects or where I²C bus loading must be minimized |
Compared with LM75BIMM-3/NOPB and MAX31820MUA+, the AD7416ARMZ-REEL offers superior noise immunity via its programmable fault queue, tighter integration with I²C-based host systems, and optimized power profile for battery-backed monitoring - making it ideal for mission-critical embedded thermal supervision where reliability and interface simplicity are prioritized.

FAQ
What is the primary function of the AD7416ARMZ-REEL?
The AD7416ARMZ-REEL is a dedicated 10-bit digital temperature sensor IC with integrated I²C interface and overtemperature indicator (OTI) output. It performs no analog-to-digital conversion of external signals - its sole function is high-accuracy ambient temperature measurement across −40°C to +125°C, with ±2°C error at room temperature. The AD7416ARMZ-REEL does not support external analog inputs, distinguishing it from the AD7417/AD7418 family members.
Does the AD7416ARMZ-REEL require an external reference voltage?
No, the AD7416ARMZ-REEL uses an internal 2.5 V reference for its ADC and does not expose a REFIN pin. Unlike the AD7417 or AD7418, the AD7416ARMZ-REEL has no provision for external reference connection - the on-chip reference is fixed and optimized for temperature sensor performance. This simplifies design and reduces component count in thermal monitoring applications.
How is the overtemperature indicator (OTI) output configured on the AD7416ARMZ-REEL?
The OTI output on the AD7416ARMZ-REEL is an open-drain logic signal that asserts when the measured temperature exceeds the value stored in the TOTI setpoint register. Its polarity (active-high or active-low) and operating mode (comparator or interrupt) are controlled via bits in the Configuration Register. A programmable fault queue counter (1–4) further filters spurious triggers by requiring consecutive out-of-limit readings before OTI activation.
What package type is used for the AD7416ARMZ-REEL?
The AD7416ARMZ-REEL is supplied in an 8-lead MSOP (Mini Small Outline Package) with 0.65 mm lead pitch, 3 mm × 3 mm body size, and exposed thermal pad. This package is distinct from the SOIC variant (AD7416ARZ) and offers improved thermal performance and board-space efficiency - critical for compact, thermally sensitive applications like handheld medical devices and dense PCB layouts.
Can multiple AD7416ARMZ-REEL devices share the same I²C bus?
Yes, up to eight AD7416ARMZ-REEL devices can operate on a single I²C bus using the A0, A1, and A2 address-select pins. These three inputs configure the three least-significant bits of the 7-bit I²C slave address (base 0x90), enabling unique addresses from 0x90 to 0x97. No external address jumpers or resistors are needed - logic levels on A0–A2 directly determine device addressing.
