Product details
Overview
TLV2313IDGKT from Texas Instruments is a dual-channel, rail-to-rail input/output precision 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 use in battery-powered medical sensors and utility metering front-ends.
For engineers reviewing the TLV2313IDGKT datasheet, TLV2313IDGKT pinout, TLV2313IDGKT application, or TLV2313IDGKT equivalent, this page provides verified electrical specs, SOIC-8 and VSSOP-8 package mapping, temperature-stable CMRR/PSRR behavior, and real-world design guidance for single-supply signal conditioning.
Technical Context
The TLV2313IDGKT employs a complementary differential input stage enabling rail-to-rail common-mode range (–0.2 V to VS + 0.2 V) with no phase reversal, and a class AB output stage delivering rail-to-rail swing within 5 mV of rails at 100 kΩ load. Its unity-gain stability supports capacitive loads up to 1 nF without external compensation.
It integrates an internal RF/EMI filter on input pins, achieves 4-kV HBM ESD protection, and maintains 85 dB CMRR over the linear input range (VCM < VS – 1.3 V), while PSRR remains ≥74 dB across 1.8–5.5 V supply and –40°C to +125°C operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - enables direct interface with Li-ion, coin-cell, and 3.3 V/5 V logic without level-shifting. |
| Quiescent Current per Channel | 65 µA (typ) - allows continuous operation in wearable devices with multi-year battery life at 3 V. |
| Gain-Bandwidth Product | 1 MHz - supports anti-aliasing filtering and sensor signal amplification up to ~100 kHz closed-loop bandwidth. |
| Input Offset Voltage | 0.75 mV (typ) - ensures ≤0.015% error in 5 V full-scale 12-bit ADC driver applications. |
| Input Bias Current | ±1 pA - permits use with >10 MΩ source impedances (e.g., pH electrodes, piezoresistive sensors). |
| CMRR / PSRR | 85 dB / 74 dB (min) - rejects power-supply ripple and common-mode noise in noisy industrial environments. |
| Operating Temperature | –40°C to +125°C - qualified for deployment in utility meters and building automation equipment exposed to ambient extremes. |
Pinout & Package
Dual-channel TLV2313IDGKT is packaged in an 8-pin VSSOP (DGK) with 3.00 mm × 3.00 mm body size - compatible with space-constrained PCB layouts and reflow assembly. Pinout matches industry-standard dual op-amp configuration for drop-in replacement in existing designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives ADC input or transducer load; rail-to-rail swing supports full dynamic range utilization. |
| 2 | –IN A | Inverting input, channel A - connects to feedback network; high impedance (1 pA bias) minimizes loading error. |
| 3 | +IN A | Noninverting input, channel A - accepts sensor signals directly; rail-to-rail common-mode range accommodates 0–VS inputs. |
| 4 | V– | Negative supply terminal - referenced to ground in single-supply operation; must be decoupled with 100 nF ceramic capacitor. |
| 5 | +IN B | Noninverting input, channel B - independent input path enables dual-sensor monitoring or differential pair implementation. |
| 6 | –IN B | Inverting input, channel B - supports independent gain-setting resistors per channel without crosstalk. |
| 7 | OUT B | Amplifier B output - electrically isolated from OUT A; suitable for driving separate signal chains or reference buffers. |
| 8 | V+ | Positive supply terminal - accepts 1.8–5.5 V; internal EMI filter reduces sensitivity to high-frequency noise on supply rail. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Supports 0 V to VS input signals and delivers output within 5 mV of V–/V+ - eliminates need for level-shifting in single-supply systems. |
| Low 1-pA Input Bias Current | Enables accurate amplification of high-impedance sources (e.g., thermistors, photodiodes) without significant DC error. |
| Integrated RF/EMI Filter | Reduces rectification-induced offset shift from GSM/ISM-band interference - critical for reliable operation in portable medical devices. |
| Unity-Gain Stable | Operates reliably as buffer or gain-of-1 amplifier with up to 1 nF capacitive load - simplifies layout and eliminates external compensation. |
| Extended Temperature Range | Specified from –40°C to +125°C - meets industrial and utility-grade environmental requirements without derating. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Higher IQ (150 µA/ch), lower GBW (1 MHz same), no integrated EMI filter, 70°C max TA. | Limited to commercial-temperature consumer devices; unsuitable for utility metering or extended outdoor use. | Choose LMV358IDR only if cost is primary constraint and extended temperature/EMI immunity are not required. |
| OPA2313IDGKT | Pin-compatible, identical specs - TI's newer marking for same die; same SOIC/VSSOP footprint and performance. | No functional difference; OPA2313IDGKT is a rebranded variant with identical qualification and reliability data. | Select OPA2313IDGKT when sourcing new production lots - it supersedes TLV2313IDGKT with identical form-fit-function. |
Compared with LMV358IDR, TLV2313IDGKT offers 57% lower quiescent current and extended temperature support; versus OPA2313IDGKT, it is functionally identical but reflects earlier TI part numbering - both are fully interchangeable in design and procurement.

FAQ
What is the maximum capacitive load the TLV2313IDGKT can drive while maintaining stability?
The TLV2313IDGKT remains unity-gain stable with pure capacitive loads up to 1 nF. For larger loads (e.g., >10 nF), adding a 10–20 Ω series resistor between the output and capacitor restores stability by isolating the op-amp's output impedance from the reactive load. This technique is validated in TI's SBOS753B datasheet Figure 19 and applies directly to TLV2313IDGKT in VSSOP-8 packaging.
Does TLV2313IDGKT support true rail-to-rail input at 1.8 V supply?
Yes. TLV2313IDGKT guarantees rail-to-rail input operation from –0.2 V to VS + 0.2 V across its full 1.8–5.5 V supply range, including at 1.8 V. The complementary input stage ensures no phase reversal and maintains CMRR >73 dB even at minimum supply, as confirmed in Section 7.8 of the SBOS753B datasheet.
Can TLV2313IDGKT replace older dual op-amps like LM358 in existing designs?
TLV2313IDGKT is not a direct drop-in for LM358 due to different pinout (LM358 uses SOIC-8 but with V+ on pin 8 and V– on pin 4, same as TLV2313IDGKT), yet requires verification of input common-mode range and output swing compatibility. Unlike LM358, TLV2313IDGKT supports rail-to-rail I/O and draws 75% less current - making it suitable for upgrade paths where power and precision are critical.
What is the typical input voltage noise density of TLV2313IDGKT at 1 kHz?
The TLV2313IDGKT exhibits 26 nV/√Hz input voltage noise density at 1 kHz, as specified in both Sections 7.7 and 7.8 of the SBOS753B datasheet. This value is consistent across 1.8 V and 5.5 V supplies and enables high-fidelity amplification of low-level sensor signals without significant noise degradation.
Is TLV2313IDGKT qualified for automotive applications?
No. TLV2313IDGKT is specified for industrial temperature range (–40°C to +125°C) but is not AEC-Q200 qualified or automotive grade. For automotive use, TI recommends the pin-compatible OPA2991QDGKRQ1 - which shares the same VSSOP-8 package and key specs but adds automotive qualification and enhanced ESD robustness.
