Product details
Overview
TLV2314QDRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 automotive-qualified rail-to-rail input/output operational amplifier. It delivers 3 MHz gain-bandwidth, 1.5 V/µs slew rate, 0.75 mV typical offset voltage, 1 pA typical input bias current, and 250 µA maximum quiescent current per channel across 1.8 V to 5.5 V supply. It is used in battery management systems for precision low-side current sensing.
For engineers reviewing the TLV2314QDRQ1 datasheet, TLV2314QDRQ1 pinout, TLV2314QDRQ1 application, or TLV2314QDRQ1 equivalent, key selection considerations include its EMI-hardened architecture (EMIRR > 60 dB up to 1 GHz), unity-gain stability with capacitive loads ≤300 pF, extended –40°C to +125°C operation, and SOIC-8 packaging for automotive PCB layouts requiring thermal robustness and board-level reliability.
Technical Context
The TLV2314QDRQ1 employs a complementary differential input stage enabling rail-to-rail common-mode input range (–0.2 V to V+ + 0.2 V) and a Class AB output stage delivering rail-to-rail swing within 5 mV of either supply under 10-kΩ load. Its internal 80-MHz low-pass EMI filter suppresses RF rectification effects on offset voltage.
It achieves unity-gain stability without external compensation while supporting capacitive loads up to 300 pF, and features no phase reversal during overdrive. The device operates across 1.8 V to 5.5 V single-supply or ±0.9 V to ±2.75 V dual-supply configurations, with guaranteed performance over –40°C to +125°C ambient temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358QDRQ1 | Lower GBW (1 MHz), higher IQ (130 µA/ch), no integrated EMI filter, same SOIC-8 package | Limited to lower-frequency sensing (<50 kHz); less suitable for RF-noisy environments like engine bays | Choose when cost sensitivity outweighs EMI immunity and bandwidth requirements |
| OPA2314QDRQ1 | Identical architecture and specs but not AEC-Q100 certified; lacks automotive qualification documentation | Not approved for safety-critical automotive functions per ISO 26262; restricted to non-safety subsystems | Use only in non-automotive industrial or consumer applications where AEC-Q100 is not mandated |
Compared with LMV358QDRQ1 and OPA2314QDRQ1, TLV2314QDRQ1 uniquely combines AEC-Q100 Grade 1 qualification, 3-MHz bandwidth, and on-die EMI filtering-making it the only option qualified for demanding automotive low-side sensing where RF resilience and temperature robustness are mandatory.

FAQ
What is the operating temperature range for TLV2314QDRQ1?
TLV2314QDRQ1 is specified for continuous operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements for automotive under-hood and cabin applications. This range is validated across all electrical parameters including offset voltage, CMRR, and gain-bandwidth product, with no derating required at temperature extremes.
Does TLV2314QDRQ1 support single-supply operation?
Yes, TLV2314QDRQ1 supports true single-supply operation from 1.8 V to 5.5 V. Its rail-to-rail input extends 200 mV beyond both supply rails, and rail-to-rail output swings within 5 mV of V– and V+, enabling direct interfacing with grounded shunts and low-voltage ADCs without level-shifting circuitry.
What is the maximum capacitive load TLV2314QDRQ1 can drive stably?
TLV2314QDRQ1 remains unity-gain stable with capacitive loads up to 300 pF, as confirmed in TI's SBOS837A datasheet Figure 8. For larger loads, adding a 10-Ω to 20-Ω series resistor between amplifier output and capacitor reduces overshoot while maintaining functional stability in sampling applications.
Is TLV2314QDRQ1 pin-compatible with other dual-channel op-amps in SOIC-8?
No, TLV2314QDRQ1 has a non-standard SOIC-8 pinout optimized for dual independent channels: pins 1/7 are outputs, pins 2/3 and 5/6 are inverting/noninverting inputs per channel, and pins 4/8 are supplies. It is not pin-compatible with LM358, LMV358, or OPA2314 - PCB layout must follow TI's recommended footprint.
How does the internal EMI filter in TLV2314QDRQ1 improve system reliability?
The integrated 80-MHz low-pass EMI filter in TLV2314QDRQ1 attenuates RF energy before it reaches the input stage, reducing rectification-induced offset voltage shifts by >60 dB at 100 MHz. This prevents erroneous readings in battery monitors and safety sensors exposed to cellular, Bluetooth, or radar emissions in modern vehicles.
