Product details
Overview
TLV2372QDRG4Q1 from Texas Instruments is a dual-channel, rail-to-rail input and output automotive-grade operational amplifier designed for precision signal conditioning in engine control units, battery management systems, and HEV/EV inverters. It delivers 3 MHz gain-bandwidth, 2.4 V/µs slew rate, 550 µA/channel supply current, 39 nV/√Hz input noise voltage, and operates from 2.7 V to 16 V across –40°C to 125°C.
For engineers reviewing the TLV2372QDRG4Q1 datasheet, TLV2372QDRG4Q1 pinout, TLV2372QDRG4Q1 application, or TLV2372QDRG4Q1 equivalent, key selection criteria include rail-to-rail I/O capability at low quiescent current, AEC-Q100 Grade 1 qualification, ultra-low input bias current (1 pA), high CMRR (up to 84 dB), and SOIC-8 packaging for automotive board-level reliability.
Technical Context
The TLV2372QDRG4Q1 uses CMOS input stage architecture enabling 1 pA input bias current and rail-to-rail common-mode input range up to the supply rails. Its internal Class AB output stage supports rail-to-rail output swing with ±100 mA short-circuit current capability and maintains stability with capacitive loads up to 100 pF.
It features no phase reversal under overdrive conditions due to high common-mode input voltage tolerance (0 V to VDD), and its 3 MHz unity-gain bandwidth is maintained across 2.7–16 V supply range and full automotive temperature range (–40°C to 125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports direct 12-V battery connection and start-stop functionality without external regulation |
| Gain-Bandwidth Product | 3 MHz - enables stable closed-loop operation up to ~200 kHz at gain = 15 for sensor signal amplification |
| Slew Rate | 2.4 V/µs - ensures <3 µs 0.1% settling for 1-V step, suitable for fast transient detection in motor control |
| Input Offset Voltage | 4.5 mV (typ) - enables accurate DC-coupled current sensing with ≤0.5% error at 100-mV sense voltage |
| Input Bias Current | 1 pA (typ) - minimizes voltage error in high-impedance sensor interfaces (e.g., thermistors, pH electrodes) |
| Common-Mode Rejection | 84 dB (max) - suppresses battery rail noise in differential measurements within ECU analog front-ends |
| Quiescent Current | 550 µA per channel - allows dual op-amp use in always-on BMS monitoring without excessive standby drain |
Pinout & Package
TLV2372QDRG4Q1 is packaged in an 8-pin SOIC (D package) with nominal body size 4.90 mm × 3.91 mm, optimized for automotive PCB thermal dissipation and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN– | Inverting input, channel 1 | Accepts feedback or inverted signal path; referenced to GND for single-supply configurations |
| 1IN+ | Noninverting input, channel 1 | Primary sensor interface node; supports rail-to-rail common-mode range (0 V to VDD) |
| 1OUT | Output, channel 1 | Rail-to-rail swing (within 100 mV of rails at 1 mA); drives ADC inputs or downstream comparators |
| 2IN– | Inverting input, channel 2 | Independent second channel input; electrically isolated from channel 1 except shared power/ground |
| 2IN+ | Noninverting input, channel 2 | Enables dual-sensor processing (e.g., current + voltage sensing) on single IC |
| 2OUT | Output, channel 2 | Full rail-to-rail output drive; supports independent gain stages without cross-talk degradation |
| GND | Negative (lowest) power supply | System ground reference; must be low-impedance return path for both channels' bias and load currents |
| VDD | Positive power supply | Single 2.7–16 V rail; powers both amplifiers; requires local 100-nF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|

| 1 pA input bias current | Enables high-precision interfacing with megohm-range sensors without offset drift |
| 39 nV/√Hz input voltage noise | Supports low-noise amplification of µV-level signals (e.g., thermocouples, strain gauges) |
| No phase reversal on overdrive | Prevents latch-up or erroneous output during input transients beyond supply rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2272QDR | Lower bandwidth (2.2 MHz), higher supply current (1100 µA/ch), output-only rail-to-rail | Less suitable for high-speed current sensing; better for low-noise audio preamps | Choose when lower cost outweighs bandwidth and quiescent current requirements |

FAQ
What is the operating temperature range for TLV2372QDRG4Q1?
The TLV2372QDRG4Q1 is qualified per AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. This range is validated for placement in engine compartments, battery enclosures, and powertrain control modules where thermal stress is extreme.
Does TLV2372QDRG4Q1 support rail-to-rail input and output simultaneously?
Yes, TLV2372QDRG4Q1 supports true rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 100 mV of VDD and GND at 1 mA load). This enables full utilization of ADC input ranges in single-supply 3.3-V or 5-V systems without external level-shifting circuitry.
What is the maximum capacitive load TLV2372QDRG4Q1 can drive stably?
TLV2372QDRG4Q1 maintains phase margin ≥65° with capacitive loads up to 100 pF when configured as a unity-gain buffer (AV = 1), per Figure 19 in the datasheet. For loads >100 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to preserve stability.
Is TLV2372QDRG4Q1 pin-compatible with standard TLV2372 variants?
Yes, TLV2372QDRG4Q1 uses the same SOIC-8 (D) package and identical pinout as non-automotive TLV2372 variants. However, it includes enhanced ESD protection (HBM ±2000 V, CDM ±500 V) and extended temperature validation - making it a drop-in replacement where automotive qualification is required.
What is the typical input offset voltage drift of TLV2372QDRG4Q1 over temperature?
The TLV2372QDRG4Q1 has a typical input offset voltage drift of 2 µV/°C, measured over the full –40°C to +125°C range. This low drift ensures minimal calibration drift in precision current sensing and sensor front-end applications across automotive thermal cycles.
