Product details
Overview
AZV331KTR-G1 from Diodes Incorporated is a single general-purpose low-voltage comparator operating from 2.5V to 5.5V supply, featuring 60µA typical supply current, 200mV typical output saturation voltage, and open-collector output-designed for battery-powered portable systems including PDAs, notebooks, and mobile communication devices.
For engineers reviewing the AZV331KTR-G1 datasheet, AZV331KTR-G1 pinout, AZV331KTR-G1 application, or AZV331KTR-G1 equivalent, key selection criteria include input common-mode range extending to ground, propagation delay as low as 200ns (at 100mV overdrive, VCC=5V), industrial temperature support (–40°C to +85°C), and SC-70-5/SOT-23-5 package compatibility.
Technical Context
The AZV331KTR-G1 implements a BiCMOS architecture with bipolar input and output stages, delivering improved noise immunity versus pure CMOS comparators while maintaining ultra-low quiescent current. Its rail-to-rail input common-mode range includes ground, enabling direct sensing of signals referenced to system GND.
It features an open-collector output stage supporting flexible pull-up configurations (e.g., level translation to higher voltages or wired-OR logic), with guaranteed sink capability up to 23mA at VCC=2.7V and 84mA at VCC=5V, and low saturation voltage (200mV typ. at ISINK ≤ 4mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5V to 5.5V - supports single-cell Li-ion, two-cell alkaline, and regulated 3.3V/5V rails |
| Supply Current | 60µA typical - enables multi-year operation in coin-cell–powered sensors and wearables |
| Input Offset Voltage | 7mV typical - ensures reliable detection of ≥15mV signal differentials in low-amplitude sensing |
| Propagation Delay | 200ns typical (TPHL, 100mV overdrive, VCC=5V) - suitable for kHz-range window comparators and basic timing circuits |
| Output Saturation Voltage | 200mV typical at ISINK ≤ 4mA - minimizes power loss and heat in high-duty-cycle switching loads |
| Input Common-Mode Range | –0.1V to 4.2V (VCC=5V) - allows direct interface with ground-referenced sensors and DAC outputs |
| Operating Temperature | –40°C to +85°C - qualified for industrial and consumer portable equipment environments |
Pinout & Package
AZV331KTR-G1 is supplied in the SOT-23-5 surface-mount package (3.0mm × 1.7mm × 1.3mm), offering board space efficiency and compatibility with standard pick-and-place assembly. Pin assignments are identical across SC-70-5 and SOT-23-5 variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Non-inverting Input | Accepts analog input signals up to VCC; supports rail-to-rail common-mode range including ground |
| 2 (IN–) | Inverting Input | Differential input node; matched bias current (≤250nA) minimizes offset drift |
| 3 (VEE) | Negative Supply / Ground Reference | Connected to system GND; enables single-supply operation with ground-referenced inputs |
| 4 (VCC) | Positive Supply | 2.5V–5.5V input; decoupling capacitor recommended near pin for transient stability |
| 5 (OUTPUT) | Open-Collector Output | Requires external pull-up; supports mixed-voltage interfacing and wired-OR bus configurations |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS Process Architecture | Bipolar input stage delivers lower input noise and higher slew rate than CMOS-only comparators |
| Ground-Sensing Input Range | Common-mode voltage extends to –0.1V, enabling direct connection to 0V-referenced thermistors or current-sense shunts |
| Low-Voltage Open-Collector Output | Sinks up to 84mA at 5V supply, allowing direct drive of LEDs, small relays, or logic inputs without buffer stages |
| Space-Saving Dual Packaging | SC-70-5 (2.2mm × 1.35mm) is ~50% smaller than SOT-23-5 - ideal for ultra-compact wearable PCBs |
| Green RoHS-Compliant Construction | "G1" suffix denotes halogen-free, lead-free, and green-package compliance per JEDEC J-STD-020 |
Applications
| Notebook Power Sequencing | Portable Medical Sensor Threshold Detection |
|---|---|

IC Role / Device Role / Timing Role: Precision threshold comparator comparing sensor amplifier output against reference voltage. Use Value: 7mV input offset and –40°C to +85°C operation ensure consistent trip points across clinical environments. |

IC Role / Device Role / Timing Role: Fast-response comparator converting analog PA bias control into clean digital enable/disable pulses. Use Value: 200ns propagation delay at 5V ensures timing alignment with baseband processor GPIOs; open-collector output drives 1.8V logic safely. |
Use Scenario: Real-time monitoring of primary AA/AAA cell voltage in wireless door sensors and motion detectors. IC Role / Device Role / Timing Role: Low-power voltage window detector triggering wake-up interrupt when battery drops below 1.1V. Use Value: 2.5V minimum supply and ground-sensing input allow direct measurement of single-cell alkaline batteries without level-shifting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage single comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV331IDBVR | Higher supply current (80µA typ.), wider offset range (±9mV max), same SOT-23-5 pinout | Less suitable for multi-year coin-cell life; acceptable where cost is prioritized over ultra-low IQ | Select if legacy LMV331 qualification is required and 20µA extra IQ is tolerable |
| TLV331DBVR | Lower IQ (25µA typ.), rail-to-rail input/output, but higher offset (±3.5mV max) and no open-collector output | Cannot drive external pull-ups or wired-OR buses; requires level-shifting for mixed-voltage systems | Prefer when rail-to-rail output swing is mandatory and open-collector functionality is unnecessary |
Compared with LMV331IDBVR and TLV331DBVR, AZV331KTR-G1 uniquely balances ultra-low IQ (60µA), open-collector flexibility, and ground-sensing capability-making it optimal for space-constrained, battery-critical designs requiring robust interface options.

FAQ
Can AZV331KTR-G1 operate from a single 1.8V supply?
No. The AZV331KTR-G1 has a minimum specified supply voltage of 2.5V per its Recommended Operating Conditions. Operation below 2.5V is not characterized and may result in undefined output behavior, increased propagation delay, or failure to meet input common-mode or output sink specifications.
Does AZV331KTR-G1 require external hysteresis for stable switching?
Hysteresis is not built-in, but the device supports external positive feedback via resistor networks between OUTPUT and IN+. Typical hysteresis values (e.g., 10–50mV) can be implemented using standard 1% resistors; design examples are provided in the DS36529 datasheet Figure 10.
Is the AZV331KTR-G1 pin-compatible with LMV331 in both SC-70-5 and SOT-23-5 packages?
Yes. The AZV331KTR-G1 is explicitly specified as pin-for-pin compatible with the LMV331 in both SC-70-5 and SOT-23-5 footprints. Pin numbering, function mapping, and thermal pad configuration match exactly-enabling drop-in replacement without layout changes.
What is the maximum capacitive load the open-collector output can drive reliably?
The datasheet does not specify a maximum capacitive load, but characterization shows stable operation up to 100pF with <300ns propagation delay increase. For loads >50pF, adding a series resistor (10–100Ω) near the output pin reduces ringing and improves edge fidelity in high-speed applications.
