Product details
Overview
TLV2313QDRQ1 from Texas Instruments is a dual-channel, automotive-grade rail-to-rail input/output operational amplifier optimized for cost-sensitive, low-power systems. It delivers 1 MHz gain-bandwidth, 65 µA/ch quiescent current, 0.75 mV typical offset voltage, and operates from 1.8 V to 5.5 V - enabling precision signal conditioning in battery-powered automotive sensors and control loops.
For engineers reviewing the TLV2313QDRQ1 datasheet, TLV2313QDRQ1 pinout, TLV2313QDRQ1 application, or TLV2313QDRQ1 equivalent, this page provides verified technical context, package-specific pin functions, real-world automotive use cases, and validated alternative options - all grounded in TI's SBOS884A production data sheet.
Technical Context
The TLV2313QDRQ1 implements a complementary differential input stage (N- and P-channel pairs) enabling true rail-to-rail input operation with ±200 mV beyond supply rails, though CMRR and PSRR degrade within the (V+) – 1.7 V to (V+) – 0.9 V transition region. Its class AB output stage achieves 5 mV rail-to-rail swing into 100 kΩ loads at 1.8–5.5 V supply.
It features integrated RFI/EMI filtering (35 MHz common-mode cutoff), unity-gain stability with ≤100 pF capacitive loads, no phase reversal under overdrive, and AEC-Q100 Grade 1 qualification (–40°C to +125°C ambient). Input bias current is 1 pA, supporting high-impedance sensor interfaces like capacitive sensing and battery monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports single-cell Li-ion, 3.3 V, and 5 V automotive domains without level shifting. |
| Gain Bandwidth Product | 1 MHz - enables stable closed-loop operation up to ~100 kHz with G = 10, suitable for ADC driver and sensor signal chain bandwidths. |
| Quiescent Current | 65 µA per channel - allows continuous operation in always-on vehicle modules with sub-150 µA total system bias. |
| Input Offset Voltage | 0.75 mV typical - ensures <±1 LSB error when driving 12-bit SAR ADCs with 2.048 V reference. |
| Input Bias Current | 1 pA - permits use with >10 MΩ source impedances (e.g., thermistors, piezoresistive sensors) without significant voltage drop. |
| EMI Rejection Ratio | ≥100 dB at 100 MHz - suppresses RF-induced DC offset shifts in infotainment and radar proximity circuits. |
| Common-Mode Range | (V−) − 0.2 V to (V+) + 0.2 V - enables direct interface to ground-referenced sensors and rail-sampled inputs. |
Pinout & Package
TLV2313QDRQ1 is packaged in an SOIC-8 (D) body measuring 4.90 mm × 3.91 mm, rated for surface-mount reflow and automotive thermal cycling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT_A | Output, Channel A | Class AB buffered output capable of sourcing/sinking ±15 mA; swings to within 5 mV of rails into 100 kΩ. |
| 2: –IN_A | Inverting Input, Channel A | Differential node with 1 pA bias current; accepts signals from (V−) − 0.2 V to (V+) + 0.2 V. |
| 3: +IN_A | Noninverting Input, Channel A | Complementary input pair node; used for unity-gain buffers and high-Z sensor interfaces. |
| 4: V− | Negative Supply Rail | Reference for both channels; must be connected to lowest system potential (e.g., GND or –VS). |
| 5: +IN_B | Noninverting Input, Channel B | Independent input for second channel; electrically isolated from Channel A except via shared supplies. |
| 6: –IN_B | Inverting Input, Channel B | Matches Channel A specs; supports dual-sensor differential measurement or independent signal paths. |
| 7: OUT_B | Output, Channel B | Identical drive capability to OUT_A; enables dual-path signal conditioning without cross-talk. |
| 8: V+ | Positive Supply Rail | Primary power connection; supports 1.8–5.5 V operation; internal ESD diodes clamp to this rail. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Enables full dynamic range utilization in single-supply systems (e.g., 3.3 V microcontroller ADCs) without external level-shifting circuitry. |
| AEC-Q100 Grade 1 Qualification | Validated for –40°C to +125°C ambient operation, meeting automotive engine bay and cabin module reliability requirements. |
| Integrated RFI/EMI Filter | 35 MHz common-mode low-pass filter reduces rectified offset drift from GSM, Bluetooth, and AM/FM band interference. |
| Unity-Gain Stable | Operates reliably as a voltage follower or buffer without external compensation, simplifying layout for sensor front-ends. |
| No Phase Reversal | Prevents catastrophic output inversion during input overdrive - critical for safety-critical feedback loops in motor control. |
Applications

|---|---|
|
Use Scenario: Amplifying low-level microphone or line-in signals in head unit audio processors before ADC sampling. IC Role / Device Role / Timing Role: Dual-channel precision buffer and gain stage; Channel A handles left channel, Channel B right channel.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, rail-to-rail, low-power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358QDRQ1 | Higher IQ (130 µA/ch), lower GBW (1.4 MHz), no integrated EMI filter, same SOIC-8 package. | Less suited for RF-noisy environments (e.g., infotainment); acceptable for non-safety-critical ECU analog stages. | Choose LMV358QDRQ1 only if higher bandwidth is required and EMI immunity is not critical. |
| MCP6022-E/SN | Higher offset (1.5 mV), higher noise (31 nV/√Hz), wider supply (2.7–5.5 V), same pinout but not AEC-Q100 qualified. | Not approved for automotive production; limited to industrial or aftermarket designs without functional safety requirements. | Select MCP6022-E/SN only for non-automotive applications where AEC-Q100 compliance is unnecessary. |
Compared with TLV2313QDRQ1, LMV358QDRQ1 trades EMI robustness for marginally higher bandwidth, while MCP6022-E/SN lacks automotive qualification and exhibits higher offset/noise - making TLV2313QDRQ1 the optimal choice for AEC-Q100-compliant, noise-immune dual-channel signal conditioning.

FAQ
What is the operating temperature range for TLV2313QDRQ1?
The TLV2313QDRQ1 is AEC-Q100 Grade 1 qualified and specified for continuous operation from –40°C to +125°C ambient temperature. This range covers under-hood engine control units, cabin infotainment systems, and battery pack monitoring modules. Thermal metrics (e.g., RθJA = 131.6°C/W for SOIC-8) confirm safe junction temperatures under typical automotive power dissipation conditions.
Does TLV2313QDRQ1 support rail-to-rail input at 1.8 V supply?
Yes, TLV2313QDRQ1 maintains rail-to-rail input operation down to 1.8 V supply, with common-mode range extending from (V−) − 0.2 V to (V+) + 0.2 V. At 1.8 V, it retains 0.75 mV typical offset and 0.9 MHz gain-bandwidth - enabling precision sensing in ultra-low-voltage automotive subsystems such as tire pressure monitors and smart junction boxes.
Can TLV2313QDRQ1 drive a 100-pF capacitive load stably?
Yes, TLV2313QDRQ1 is unity-gain stable with capacitive loads up to 100 pF, as confirmed in TI's SBOS884A datasheet. Its phase margin remains ≥65° under these conditions. For loads exceeding 100 pF (e.g., long PCB traces or ADC input capacitance), adding a 10–20 Ω series resistor at the output restores stability without compromising DC accuracy in most automotive signal chains.
Is TLV2313QDRQ1 pin-compatible with other dual op amps in SOIC-8?
No - TLV2313QDRQ1 uses a non-standard SOIC-8 pinout: V− is on Pin 4 and V+ on Pin 8, unlike industry-standard dual op amps (e.g., LM358) where V+ is Pin 8 and V− is Pin 4. Swapping TLV2313QDRQ1 into existing layouts requires PCB revision. Always verify pin mapping using TI's official pin function table before design reuse.
What ESD protection does TLV2313QDRQ1 provide?
TLV2313QDRQ1 features integrated ESD protection rated at ±4000 V HBM (Human Body Model) and ±1000 V CDM (Charged Device Model), per AEC-Q100 requirements. Internal steering diodes clamp input pins to V+ and V− rails, allowing in-circuit overvoltage protection up to ±10 mA - eliminating need for external TVS diodes in most automotive sensor interfaces.
