Product details
Overview
TLV2313QDGKRQ1 from Texas Instruments is a dual-channel, automotive-grade rail-to-rail input/output operational amplifier optimized for low-power, cost-sensitive systems. It delivers 1 MHz gain-bandwidth, 65 µA/ch quiescent current, and 750 µV typical input offset voltage, enabling precision signal conditioning in battery-powered automotive sensors and control loops.
For engineers reviewing the TLV2313QDGKRQ1 datasheet, TLV2313QDGKRQ1 pinout, TLV2313QDGKRQ1 application, or TLV2313QDGKRQ1 equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade specifications (AEC-Q100 Grade 1), and real-world application constraints - all specific to the VSSOP-8 packaged TLV2313-Q1 variant.
Technical Context
The TLV2313QDGKRQ1 implements a complementary differential input stage (N- and P-channel pairs) enabling 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 integrates an internal RFI/EMI filter with ~35 MHz common-mode cutoff and demonstrates 120 dB EMIRR at 10 MHz, supporting robust operation in noisy automotive environments. Unity-gain stability is maintained up to 100 pF capacitive load; stability with ≥1 nF loads requires external series output resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct connection to 2S Li-ion, 3.3 V, and 5 V automotive rails without regulation. |
| Quiescent Current | 65 µA per channel - enables always-on sensing in low-power ECU subsystems with <130 µA total IQ. |
| Gain-Bandwidth Product | 1 MHz - sufficient for anti-aliasing filtering before 100 kSPS ADCs and closed-loop control up to ~10 kHz. |
| Input Offset Voltage | 0.75 mV (typ) - enables accurate DC-coupled amplification of mV-level sensor outputs (e.g., thermistors, strain gauges). |
| Input Bias Current | 1 pA (max) - permits use with >10 MΩ source impedances (e.g., capacitive touch, high-Z pH sensors). |
| EMI Rejection Ratio | 120 dB at 10 MHz - suppresses RF rectification-induced offset shifts in infotainment and radar proximity circuits. |
| Operating Temperature | –40°C to +125°C ambient - qualified per AEC-Q100 Grade 1 for under-hood and cabin ECU deployment. |
Pinout & Package
VSSOP-8 (DGK) package: 3.00 mm × 3.00 mm body, 0.65 mm lead pitch, exposed thermal pad (not electrically connected), RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT_A | Output, Channel A | Amplified output signal for first op-amp; capable of sourcing/sinking ±6 mA (1.8 V) or ±15 mA (5.5 V). |
| 2: –IN_A | Inverting Input, Channel A | High-impedance node (1 pA bias) accepting feedback network for inverting configurations. |
| 3: +IN_A | Noninverting Input, Channel A | High-impedance node accepting reference or sensor signal; supports common-mode range to V– – 0.2 V and V+ + 0.2 V. |
| 4: V– | Negative Supply Rail | Lowest potential supply terminal; must be connected to system ground or negative rail (e.g., –1.8 V in split-supply). |
| 5: +IN_B | Noninverting Input, Channel B | Independent input for second op-amp; electrically isolated from Channel A except via shared supplies. |
| 6: –IN_B | Inverting Input, Channel B | Feedback node for Channel B; no crosstalk with Channel A inputs under normal operation. |
| 7: OUT_B | Output, Channel B | Second independent output; rail-to-rail swing capability identical to OUT_A. |
| 8: V+ | Positive Supply Rail | Highest potential supply terminal; accepts 1.8–5.5 V; decoupling capacitor required within 1 cm for EMI immunity. |
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 ADC interface) without level-shifting circuitry. |
| AEC-Q100 Grade 1 Qualification | Validated for automotive ambient temperatures (–40°C to +125°C), HBM ±4 kV, CDM ±1 kV - reduces qualification burden for Tier 1 suppliers. |
| Integrated RFI/EMI Filter | Reduces susceptibility to GSM, Bluetooth, and AM/FM band interference, eliminating need for external RC filters on IN+ pins. |
| No Phase Reversal in Overdrive | Prevents latch-up or erroneous logic states when input exceeds supply rails - critical for fault-tolerant sensor monitoring. |
| Unity-Gain Stable | Supports buffer, active filter, and transimpedance configurations without external compensation components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, rail-to-rail, automotive op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM7332QMA/NOPB | Higher IQ (1.1 mA/ch), wider GBW (20 MHz), no integrated EMI filter, SOIC-8 only. | Better for high-speed control loops but unsuitable for ultra-low-power always-on monitoring. | Select when bandwidth >5 MHz is required and EMI immunity is managed externally. |
| MCP6022-E/SN | Non-automotive grade (industrial temp only), lower offset (250 µV typ), no AEC-Q100, same VSSOP-8 footprint. | Lacks automotive qualification; requires full system-level requalification for automotive use. | Consider only for non-safety-critical prototyping or cost-sensitive non-automotive designs. |
Compared with LM7332QMA/NOPB and MCP6022-E/SN, TLV2313QDGKRQ1 uniquely balances AEC-Q100 compliance, 65 µA/ch ultra-low power, and integrated EMI filtering - making it the only qualified option for production automotive sensor interfaces where both power budget and EMC robustness are constrained.

FAQ
What is the maximum capacitive load the TLV2313QDGKRQ1 can drive while maintaining stability?
The TLV2313QDGKRQ1 remains unity-gain stable with up to 100 pF pure capacitive load. For loads exceeding 100 pF (e.g., >1 nF), stability requires adding a 10 Ω to 20 Ω series resistor between the output and the capacitor. This technique mitigates overshoot but introduces gain error due to voltage division with parallel load resistance. The TLV2313QDGKRQ1 datasheet Figure 19 details this implementation.
Does the TLV2313QDGKRQ1 support true rail-to-rail input at 1.8 V supply?
Yes. The TLV2313QDGKRQ1 maintains rail-to-rail input operation down to 1.8 V, with common-mode range extending to (V–) – 0.2 V and (V+) + 0.2 V. At 1.8 V, the input stage transitions between N- and P-channel pairs within (V+) – 1.7 V to (V+) – 0.9 V, and CMRR remains ≥73 dB across the full range - confirmed in Section 7.7 of the TLV2313QDGKRQ1 datasheet.
What is the thermal performance of the TLV2313QDGKRQ1 in VSSOP-8 (DGK) package?
In the VSSOP-8 (DGK) package, the TLV2313QDGKRQ1 has a junction-to-ambient thermal resistance (RθJA) of 186.0°C/W and junction-to-board resistance (RθJB) of 107.3°C/W. These values assume standard JEDEC 2-layer board conditions. For sustained operation at 125°C ambient, power dissipation must remain below ~12 mW per channel to avoid exceeding 150°C junction temperature - consistent with its 65 µA/ch IQ at 5.5 V.
How does the internal EMI filter in the TLV2313QDGKRQ1 improve system-level EMC?
The TLV2313QDGKRQ1's integrated low-pass filter provides ~35 MHz common-mode cutoff and delivers 120 dB EMIRR at 10 MHz, directly reducing RF rectification-induced DC offset shifts on IN+ pins. This eliminates the need for discrete RC filters in infotainment and ADAS sensor front-ends, simplifying layout and improving immunity to cellular, WiFi, and radar band interference without sacrificing bandwidth for signal path.
Is the TLV2313QDGKRQ1 pin-compatible with other dual op-amps in VSSOP-8?
No. The TLV2313QDGKRQ1 uses a non-standard VSSOP-8 pinout: Pin 4 is V–, Pin 8 is V+, and channels are arranged as OUT_A/–IN_A/+IN_A/V– on left side and +IN_B/–IN_B/OUT_B/V+ on right side. It is not pin-compatible with industry-standard dual op-amps like LMV358 or MCP6022, which place V+ and V– on opposite corners. PCB layout must follow TI's DGK pin mapping.
