Product details
Overview
TLV316IDBVT from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-voltage, low-power precision signal conditioning. It delivers 10 MHz unity-gain bandwidth, 400 µA quiescent current per channel, and 12 nV/√Hz input voltage noise at 1 kHz - enabling high-fidelity amplification in battery-powered medical sensors and portable audio front-ends.
For engineers reviewing the TLV316IDBVT datasheet, TLV316IDBVT pinout, TLV316IDBVT application, or TLV316IDBVT equivalent, this page provides verified package mapping (SOT-23-5), confirmed thermal metrics (RθJA = 221.7°C/W), validated rail-to-rail I/O swing (≤35 mV from rails at 10 kΩ), and two documented alternative op-amps with quantified trade-offs in bandwidth, noise, and supply range.
Technical Context
The TLV316IDBVT employs a complementary differential input stage (N- and P-channel pairs) to achieve rail-to-rail common-mode input range extending 200 mV beyond V+ and V− at supplies ≥2.5 V. Its class AB output stage drives resistive loads down to 10 kΩ while maintaining ≤35 mV output voltage swing from either rail.
It integrates an internal RFI/EMI filter with ≈80 MHz –3 dB cutoff and 20 dB/decade roll-off, directly improving immunity to cellular and Wi-Fi band interference. The device is unity-gain stable and exhibits no phase reversal under overdrive, with overload recovery time of 0.8 µs and 6 V/µs slew rate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 10 MHz - supports stable closed-loop operation up to 10 MHz at G = +1, suitable for anti-aliasing filters before 1-MSPS ADCs. |
| Quiescent Current | 400 µA/ch - enables >100-hour runtime on a 40-mAh coin cell in always-on sensor nodes. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - preserves SNR in low-level thermocouple or bridge sensor amplification. |
| Input Bias Current | ±10 pA - allows use with >10 MΩ source impedances without significant offset error. |
| Offset Voltage | ±0.75 mV (typ) - ensures <1 LSB error when driving 12-bit SAR ADCs with 3.3-V reference. |
| Supply Range | 1.8 V to 5.5 V - operates directly from single Li-ion cells (3.0–4.2 V) or 3.3-V/5-V rails without LDO. |
| CMRR | 90 dB (min) - rejects common-mode noise in noisy industrial environments with unshielded wiring. |
Pinout & Package
TLV316IDBVT is packaged in a 5-pin SOT-23 (DBV) footprint measuring 1.60 mm × 2.90 mm, with exposed pad omitted. Thermal resistance is RθJA = 221.7°C/W, making it suitable for compact PCB layouts with moderate power dissipation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output node; capable of rail-to-rail swing within 35 mV of V+ or V− into 10 kΩ load. |
| 2 | V− | Negative supply or ground reference; must be connected for proper biasing of input stage. |
| 3 | +IN | Noninverting input; accepts common-mode voltages from (V−) − 0.2 V to (V+) + 0.2 V. |
| 4 | −IN | Inverting input; used for feedback configuration and gain-setting networks. |
| 5 | V+ | Positive supply; supports operation from 1.8 V to 5.5 V with stable IQ across temperature. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA316IDBVT | Higher 10-MHz GBP but 500 µA IQ; 11 nV/√Hz noise; same SOT-23-5 package. | Better AC performance at cost of 25% higher supply current - preferred for high-speed active filters. | Select OPA316IDBVT when bandwidth margin >2× required and battery life is secondary to signal fidelity. |
| TLV9001IDBVT | Lower 1-MHz GBP, 170 µA IQ, 30 nV/√Hz noise; rail-to-rail I/O; same DBV package. | Optimized for ultra-low power, not high speed - suited for sub-100-kHz sensor interfaces with strict µA budgets. | Select TLV9001IDBVT when operating frequency <100 kHz and quiescent current must stay below 200 µA. |
Compared with TLV316IDBVT, OPA316IDBVT trades 100 µA extra current for marginally lower noise and identical bandwidth, while TLV9001IDBVT sacrifices 90% bandwidth to cut IQ by 58% - making TLV316IDBVT the optimal balance for 100-kHz–1-MHz precision amplification at 400 µA.

FAQ
What is the maximum capacitive load the TLV316IDBVT can drive stably in unity-gain configuration?
The TLV316IDBVT remains stable driving up to 100 pF in unity-gain buffer configuration, as verified in Figure 7 of the SBOS752A datasheet. For larger loads (e.g., 500 pF), adding a 10-Ω series resistor at the output restores stability by isolating the capacitive reactance from the feedback loop - though this introduces minor gain error due to voltage division with the load.
Does the TLV316IDBVT support true single-supply operation down to 1.8 V?
Yes, the TLV316IDBVT is fully specified and tested from 1.8 V to 5.5 V supply. At 1.8 V, it maintains 10 MHz GBP, 400 µA IQ, and rail-to-rail input/output swing - enabling direct interface with 1.8-V microcontrollers and ADCs without level-shifting circuitry.
How does the internal RFI/EMI filter in the TLV316IDBVT improve system-level immunity?
The TLV316IDBVT's integrated 80-MHz low-pass filter attenuates RF energy before it reaches the input transistors, reducing rectified DC offset shifts caused by 900-MHz GSM or 2.4-GHz Wi-Fi signals. Measured EMIRR exceeds 60 dB at 900 MHz, preventing false triggers in sensitive sensor nodes near wireless transceivers.
Can the TLV316IDBVT replace older op-amps like the LMV321 in existing designs?
TLV316IDBVT is pin-compatible with LMV321 in SOT-23-5 (DBV) packages and offers superior specs: 10× higher bandwidth (10 MHz vs 1 MHz), 50% lower noise (12 nV/√Hz vs 23 nV/√Hz), and rail-to-rail I/O versus LMV321's limited input range. No PCB changes are required, but verify layout grounding for improved EMI rejection.
What is the guaranteed output voltage swing for TLV316IDBVT at 3.3-V supply with 10-kΩ load?
At VS = 3.3 V and RL = 10 kΩ, the TLV316IDBVT guarantees output swing within 35 mV of both rails (i.e., 35 mV ≤ VOUT ≤ 3.265 V), per Electrical Characteristics Table in SBOS752A. This rail-to-rail capability maximizes dynamic range for 12-bit ADC interfacing without external charge pumps.
