Product details
Overview
TLV313IDBVR from Texas Instruments is a single-channel, rail-to-rail input/output precision operational amplifier optimized for low-power, cost-sensitive systems. It delivers 1-MHz gain bandwidth, 65 µA typical quiescent current per channel, 26 nV/√Hz input voltage noise at 1 kHz, 0.75 mV typical input offset voltage, and operates from 1.8 V to 5.5 V supply - enabling high-accuracy signal conditioning in battery-powered medical sensors and utility metering front-ends.
For engineers reviewing the TLV313IDBVR datasheet, TLV313IDBVR pinout, TLV313IDBVR application, or TLV313IDBVR equivalent, this page provides verified specifications, package mapping, real-world use cases, and validated alternative options - all confirmed against TI's SBOS753B production data sheet and official orderable information.
Technical Context
The TLV313IDBVR employs a complementary differential input stage (N- and P-channel pairs) enabling true rail-to-rail common-mode input range extending 200 mV beyond both supply rails. Its class AB output stage achieves rail-to-rail output swing - typically within 5 mV of either rail under 100-kΩ load - while maintaining unity-gain stability with capacitive loads up to 1 nF.
It integrates an internal RF/EMI rejection filter on input pins and features no phase reversal during overdrive. Electrical performance is fully specified across –40°C to +125°C, with PSRR ≥74 dB and CMRR ≥85 dB (in non-transition region), supporting robust operation in noisy industrial and portable environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.8 V to 5.5 V - supports direct interface with Li-ion, coin-cell, and 3.3 V/5 V logic without level-shifting. |
| Quiescent Current | 65 µA/ch - enables multi-year battery life in wearable health monitors and smart meters. |
| Gain Bandwidth | 1 MHz - sufficient for driving SAR ADCs (e.g., 1 MSPS, 12-bit) with <1 LSB settling error. |
| Input Offset Voltage | 0.75 mV (typ) - ensures ≤0.075% full-scale error in 1-V reference sensor amplification. |
| Input Voltage Noise | 26 nV/√Hz at 1 kHz - preserves SNR in low-level biopotential and thermistor signal chains. |
| CMRR / PSRR | ≥85 dB / ≥74 dB - rejects power-supply ripple and common-mode interference in single-supply systems. |
| Operating Temperature | –40°C to +125°C - qualified for automotive cabin modules and industrial metering enclosures. |
Pinout & Package
The TLV313IDBVR is housed in a 5-pin SOT-23 (DBV) package measuring 2.90 mm × 1.60 mm, optimized for space-constrained PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - drives ADC inputs, filters, or transducers with rail-to-rail swing capability. |
| 2 | V– | Negative supply terminal - connects to ground or negative rail; supports single-supply operation down to 1.8 V. |
| 3 | +IN | Noninverting input - high-impedance node (1 pA bias current) for sensor voltage references or buffered signals. |
| 4 | –IN | Inverting input - used in transimpedance, difference, or inverting gain configurations; matched to +IN for CMRR. |
| 5 | V+ | Positive supply terminal - accepts up to 5.5 V; supplies internal bias and output stage. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Common-mode range extends 200 mV beyond rails; output swings to within 5 mV of V+ or V– under 100-kΩ load - eliminates level-shifting in 1.8–5.5 V systems. |
| Low Input Bias Current | 1 pA (typ) - enables accurate amplification of high-impedance sources (e.g., pH electrodes, piezoresistive sensors >10 MΩ). |
| Integrated EMI Filter | On-chip low-pass filtering on input pins - reduces rectified offset drift from GSM/ISM-band RF interference without external components. |
| No Phase Reversal | Guaranteed behavior during input overdrive - prevents latch-up or erroneous control signals in sensor saturation events. |
| Unity-Gain Stable | Stable with ≥1 nF capacitive load - simplifies design of anti-aliasing filters and ADC driver stages without compensation networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA313IDBVR | Same pinout, identical DBV package; 1.8 V to 5.5 V supply; but higher IQ (75 µA vs 65 µA) and slightly higher offset (1 mV typ vs 0.75 mV). | Better slew rate (0.5 V/µs vs 0.45 V/µs at 1.8 V) - preferred for faster step-response requirements. | Select OPA313IDBVR only if marginally improved dynamic performance justifies 15% higher quiescent current. |
| MCP6001T-I/OT | Different pinout (SOT-23-5, but +IN/–IN swapped); 1.8 V to 6.0 V supply; higher noise (30 nV/√Hz), lower CMRR (70 dB), no integrated EMI filter. | Limited RF immunity and reduced DC accuracy - acceptable only in benign EMI environments with relaxed offset specs. | Choose MCP6001T-I/OT only for legacy designs where layout cannot accommodate TLV313IDBVR's pin assignment and EMI robustness is noncritical. |
Compared with OPA313IDBVR and MCP6001T-I/OT, TLV313IDBVR offers the lowest quiescent current among pin-compatible alternatives, the only one with integrated EMI filtering, and the best combination of offset voltage and CMRR for precision DC-coupled sensor interfaces.

FAQ
What is the maximum capacitive load the TLV313IDBVR can drive while remaining stable?
The TLV313IDBVR remains unity-gain stable with pure capacitive loads up to 1 nF. For larger loads (e.g., >10 nF), stability can be restored by adding a 10–20 Ω series resistor between the output and capacitor. This technique is validated in TI's SBOS753B datasheet Figure 19 and applies directly to TLV313IDBVR in SOT-23-5 packaging.
Does the TLV313IDBVR support true rail-to-rail input at 1.8 V supply?
Yes - the TLV313IDBVR maintains rail-to-rail input operation down to 1.8 V, with common-mode range extending from (V–) – 0.2 V to (V+) + 0.2 V. This is explicitly confirmed in Section 7.8 (Electrical Characteristics: 1.8 V) of the SBOS753B datasheet, where VCM = –0.2 V to +1.8 V is specified.
What is the guaranteed minimum open-loop gain of the TLV313IDBVR?
The TLV313IDBVR guarantees a minimum open-loop voltage gain of 100 dB (at 0.3 V < VO < V+ – 0.3 V, RL = 2 kΩ) and 104 dB (at 0.05 V < VO < V+ – 0.05 V, RL = 100 kΩ), as specified in Section 7.7 of the SBOS753B datasheet - ensuring predictable closed-loop accuracy in precision gain stages.
Is the TLV313IDBVR pin-compatible with other packages in the TLV313 family?
No - TLV313IDBVR uses the SOT-23-5 (DBV) package with pin 1 = OUT, pin 2 = V–, pin 3 = +IN, pin 4 = –IN, pin 5 = V+. The SC70-5 (DCK) variant shares identical pin functions but differs in footprint and thermal characteristics; direct PCB replacement requires layout revision due to body size (2.90 mm × 1.60 mm vs 2.00 mm × 1.25 mm).
How does the TLV313IDBVR handle EMI compared to standard op-amps?
The TLV313IDBVR integrates an internal RF/EMI rejection filter on its input pins - a feature explicitly documented in Section 8.3.6 of SBOS753B. This reduces rectified offset shift from GSM/ISM-band interference, unlike generic op-amps such as MCP6001, which require external RC filtering to achieve comparable immunity.
