Product details
Overview
LM339ADRG4 from Texas Instruments is a quad differential comparator IC designed for precision voltage comparison in single-supply systems. It features ±5.5 mV max input offset voltage (over temperature), 2–30 V supply range, 1.3 µs typical response time, 200 µA per comparator quiescent current, and rail-to-rail common-mode input range including ground - enabling use in power supply monitoring, motor control feedback, and industrial sensor interfaces.
For engineers reviewing the LM339ADRG4 datasheet, LM339ADRG4 pinout, LM339ADRG4 application, or LM339ADRG4 equivalent, this page delivers verified specifications, SOIC-14 package details, real-world application context, and validated alternative options - all aligned with TI's SLCS006Z (May 2025) production data sheet.
Technical Context
The LM339ADRG4 implements four independent open-collector comparators with internal ESD clamps (2 kV HBM), supporting operation from 2 V to 30 V with no phase reversal across its full common-mode input range (V– to V+ – 2 V). Its architecture enables direct interfacing with TTL, MOS, and CMOS logic via external pull-up resistors.
Each comparator exhibits low input bias current (±25 nA max), high large-signal gain (50–200 V/mV), and output sink capability up to 20 mA - making it suitable for level-shifting, window detection, and overvoltage/undervoltage protection circuits where robustness and wide supply tolerance are required.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail common-mode input range | Operates with inputs at ground or up to VCC – 2 V - eliminates need for level-shifting in single-supply sensor interfaces. |
| Open-collector outputs | Enables wired-OR logic, mixed-voltage interfacing, and programmable hysteresis via external resistor networks. |
| Low input bias current (±25 nA max) | Minimizes loading on high-impedance sources like thermistors, RTDs, or photodiode amplifiers. |
| 2 kV HBM ESD rating | Reduces risk of field failure during board assembly or system integration without added protection components. |
| Wide 2–30 V supply range | Eliminates need for dedicated LDOs in multi-rail systems - directly powered from 3.3 V, 5 V, 12 V, or 24 V rails. |
Applications
| Power Supply Monitoring | Motor Drive Protection |
|---|---|
|
Use Scenario: Real-time monitoring of +12 V and +5 V rails in server PSUs to trigger shutdown on overvoltage or undervoltage events. IC Role / Device Role / Timing Role: Quad comparator configured as dual window detector - two channels monitor each rail independently. Use Value: ±5.5 mV offset ensures tight trip thresholds; open-collector outputs interface directly with microcontroller reset inputs or FPGA I/O banks. |
Use Scenario: Detection of overcurrent in three-phase inverter legs using shunt voltage signals fed into comparator inputs. IC Role / Device Role / Timing Role: Fast-response comparator (1.3 µs) compares shunt voltage against reference to assert fault flag before IGBT damage occurs. Use Value: 20 mA sink capability drives optocoupler LEDs directly; rail-to-rail input accommodates bidirectional current sense signals. |
| Industrial Sensor Interface | Appliance Control Logic |
|
Use Scenario: Converting analog outputs from pressure transducers or temperature sensors into digital status flags for PLC input modules. IC Role / Device Role / Timing Role: Comparator acts as analog-to-digital threshold translator - one channel per sensor, with hysteresis added externally. Use Value: Low 200 µA per-comparator current enables always-on monitoring in energy-constrained edge nodes. |
Use Scenario: Detecting door-open, water-level, or temperature thresholds in washing machines and refrigerators using simple resistive divider networks. IC Role / Device Role / Timing Role: Four independent comparators handle multiple safety interlocks and operational state checks simultaneously. Use Value: SOIC-14 package fits compact control boards; 30 V absolute max rating tolerates transient spikes in noisy appliance environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad differential comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339BDR | Improved B-version: ±0.37 mV typ offset, 1 µs response, 36 V max supply, −40°C to 85°C range. | Higher precision and speed; requires no design change for most LM339A-based layouts due to SOIC-14 pin compatibility. | Select when tighter offset, faster response, or extended supply range is needed - drop-in replacement per TI documentation. |
| LM2901DR | Same pinout, −40°C to 125°C operating range, 32 V max supply, ±15 mV max offset (non-A grade). | Broadened temperature coverage suits automotive under-hood or industrial ambient conditions where LM339ADRG4's 0°C–70°C limit is insufficient. | Choose for extended temperature reliability; verify offset tolerance in final application - not a drop-in for precision-critical designs. |
Compared with LM339ADRG4, LM339BDR offers superior accuracy and speed while maintaining identical SOIC-14 packaging and pinout, whereas LM2901DR trades offset performance for wider temperature and voltage margins - enabling selection based on thermal, precision, or supply-voltage priorities.

FAQ
What is the maximum supply voltage for LM339ADRG4?
The LM339ADRG4 supports a maximum supply voltage of 30 V, as specified in its Absolute Maximum Ratings table. This rating applies to the difference between VCC and GND pins. Operation beyond 30 V risks permanent device damage, even if within the common-mode input range. The LM339ADRG4 is not rated for 36 V operation - that specification applies only to the B-version (LM339B) and LM2901 variants.
Does LM339ADRG4 have rail-to-rail input capability?
Yes, the LM339ADRG4 features a rail-to-rail common-mode input voltage range from V– (GND) up to V+ – 2 V. This allows direct comparison of signals referenced to ground or near the positive rail - critical for single-supply applications like battery monitors or sensor front-ends. However, inputs must not go more than 0.3 V below GND to avoid incorrect output states or excessive input current.
What is the typical input offset voltage of LM339ADRG4?
The LM339ADRG4 has a typical input offset voltage of ±1 mV at 25°C and a maximum of ±4 mV over the full 0°C to 70°C operating temperature range. This value is confirmed in the LMx39A electrical characteristics table (Section 6.10), distinguishing it from the higher-offset LM339 (±9 mV max) and lower-offset LM339B (±0.37 mV typ).
Can LM339ADRG4 outputs drive TTL logic directly?
Yes, LM339ADRG4 outputs are open-collector and fully compatible with TTL logic when used with an appropriate external pull-up resistor (typically 1–10 kΩ to VCC or a separate logic rail). The device can sink up to 20 mA per output, exceeding the 1.6 mA minimum sink requirement of standard TTL inputs - ensuring reliable low-state assertion without additional buffering.
Is LM339ADRG4 RoHS compliant and lead-free?
Yes, LM339ADRG4 is RoHS compliant and lead-free, as confirmed by Texas Instruments' official product folder and packaging information. The "G4" suffix denotes green (halogen-free) packaging and Pb-free terminations, meeting JEDEC J-STD-609 Category 1 requirements. Full compliance documentation is available in TI's Quality & Reliability reports for the LM339A family.
