Product details
Overview
TLV314IDBVT from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for low-power, precision signal conditioning in battery-powered systems. It delivers 3 MHz gain bandwidth, 1.5 V/µs slew rate, and 250 µA maximum quiescent current per channel while operating from 1.8 V to 5.5 V - enabling high-fidelity sensor interfacing in portable blood glucose meters and handheld test equipment.
For engineers reviewing the TLV314IDBVT datasheet, TLV314IDBVT pinout, TLV314IDBVT application, or TLV314IDBVT equivalent, key selection criteria include its 0.75 mV typical offset voltage, 1 pA typical input bias current, internal EMI filter (80 MHz cutoff), –40°C to +125°C extended temperature range, and robust 4-kV HBM ESD rating - all in a space-constrained 5-pin SOT-23 package.
Technical Context
The TLV314IDBVT employs a complementary differential input stage enabling true rail-to-rail input operation - with common-mode range extending 200 mV beyond both supply rails - and a Class AB output stage delivering rail-to-rail swing within 5 mV of either rail under 10 kΩ load. Its unity-gain stability and 65° phase margin support direct use in buffer configurations without external compensation.
Internal RF/EMI filtering (–3 dB at ~80 MHz) suppresses rectification-induced DC offset shifts from 10 MHz–6 GHz interference, validated by EMIRR IN+ measurements up to 120 dB at 100 MHz. The device maintains 72–96 dB CMRR across its full common-mode range and achieves 115 dB open-loop gain at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth | 3 MHz - supports stable closed-loop operation up to 100 kHz with gain ≥30, suitable for anti-aliasing and active filter stages before ADCs. |
| Input Offset Voltage | ±0.75 mV (typ) - enables <1 LSB error in 12-bit ADC systems with ±2.5 V full-scale input range. |
| Quiescent Current | 250 µA/Ch (max) - allows continuous operation for >1 year on a single CR2032 coin cell in ultra-low-power sensing nodes. |
| Input Bias Current | 1 pA (typ) - permits use with >10 MΩ source impedances (e.g., pH electrodes, piezoresistive sensors) without significant voltage drop. |
| EMI Rejection Ratio | ≥100 dB at 100 MHz - mitigates measurement drift in noisy industrial or medical environments with RF transceivers nearby. |
| Rail-to-Rail Output Swing | Within 5 mV of V+ or V– at 10 kΩ - maximizes dynamic range in 1.8 V–3.3 V systems, preserving >99% of ADC input span. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive sensors and industrial motor control feedback loops. |
Pinout & Package
TLV314IDBVT is housed in a 5-pin SOT-23 (DBV) package measuring 2.90 mm × 1.60 mm, optimized for high-density PCB layouts in portable instrumentation and wearable health devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Amplifier output | Class AB stage drives resistive loads ≤10 kΩ or capacitive loads ≤1 nF directly; requires series resistor for larger CL. |
| 2: V– | Negative supply rail | Connects to ground in single-supply systems (1.8–5.5 V); supports dual-supply operation down to ±0.9 V. |
| 3: +IN | Noninverting input | High-impedance node (1 pA bias) compatible with passive RC filters and high-Z sensors without loading error. |
| 4: –IN | Inverting input | Accepts feedback networks; common-mode range extends 200 mV beyond V– and V+, enabling true single-supply operation. |
| 5: V+ | Positive supply rail | Must be bypassed with 0.01 µF ceramic capacitor near pin; supports wide input common-mode and rail-swing output. |
Key Features
| Feature | Design Value |
|---|---|
| Internal EMI Filter | Integrated 80 MHz low-pass filter on inputs reduces rectified offset shift from RF interference - eliminates need for external ferrite beads or RC snubbers. |
| Rail-to-Rail Input/Output | Input common-mode range includes both supply rails; output swings to within 5 mV of V+ or V– - preserves full ADC resolution in low-voltage systems. |
| Low Input Bias Current | 1 pA typical enables accurate amplification of signals from high-impedance sources (e.g., thermistors, photodiodes) without calibration drift. |
| Unity-Gain Stability | Stable in voltage-follower configuration with ≤1 nF capacitive load - simplifies design of precision buffers for SAR ADC sample-and-hold inputs. |
| Extended Temperature Range | Specified from –40°C to +125°C with no derating - supports deployment in automotive cabin modules and industrial PLC analog I/O cards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA314AIDBVR | Same 3 MHz GBW and 250 µA IQ, but 0.15 mV max offset (vs. ±3 mV for TLV314IDBVT) and 0.01 µV/√Hz lower noise density. | Better suited for high-accuracy strain gauge bridges where offset drift dominates error budget. | Select OPA314AIDBVR when sub-mV offset and tighter drift specs are required; TLV314IDBVT remains optimal for cost-sensitive, general-purpose designs. |
| MCP6001T-E/OT | Lower 100 µA IQ but only 1 MHz GBW, 2.5 mV max offset, and no integrated EMI filter - requires external RF suppression. | Appropriate for simple DC-coupled sensor buffers where speed and EMI immunity are secondary. | Choose MCP6001T-E/OT for ultra-low-power standby modes; TLV314IDBVT provides superior AC performance and built-in EMI hardening for active measurement cycles. |
Compared with OPA314AIDBVR and MCP6001T-E/OT, TLV314IDBVT offers the best balance of EMI resilience, rail-to-rail flexibility, and extended temperature capability - making it the preferred choice for medical, portable test, and harsh-environment signal chains where reliability and noise immunity are non-negotiable.

FAQ
What is the maximum capacitive load the TLV314IDBVT can drive stably in unity-gain configuration?
The TLV314IDBVT remains unity-gain stable with pure capacitive loads up to approximately 1 nF. For larger loads, stability can be restored by adding a 10 Ω–20 Ω series resistor between the output and the capacitor - though this introduces a small gain error due to voltage division with parallel resistive loads. This behavior is documented in Figure 8 and Section 8.3.5 of the TLV314IDBVT datasheet.
Does the TLV314IDBVT support dual-supply operation, and what are the limits?
Yes, the TLV314IDBVT supports dual-supply operation from ±0.9 V to ±2.75 V (i.e., total supply range 1.8 V to 5.5 V). Its rail-to-rail input and output stages function correctly across this full range, and the specified electrical characteristics - including offset voltage, CMRR, and bandwidth - are guaranteed over the entire dual-supply operating window per Section 7.3 of the TLV314IDBVT datasheet.
How does the internal EMI filter in the TLV314IDBVT improve system-level robustness?
The TLV314IDBVT integrates an internal low-pass filter with ~80 MHz –3 dB cutoff on both input pins, reducing rectification-induced DC offset shifts caused by RF interference from 10 MHz to 6 GHz. Measured EMIRR IN+ exceeds 100 dB at 100 MHz, allowing the TLV314IDBVT to maintain measurement integrity in proximity to Wi-Fi, Bluetooth, or cellular transceivers without external filtering components.
What is the guaranteed input offset voltage specification for TLV314IDBVT over temperature?
The TLV314IDBVT has a maximum input offset voltage of ±3 mV over the full operating temperature range of –40°C to +125°C, with a typical value of ±0.75 mV at 25°C. Its offset drift is specified at 2 µV/°C maximum, ensuring predictable, low-drift performance in thermally varying environments such as automotive or industrial enclosures.
Can TLV314IDBVT operate reliably from a 1.8 V single supply, and what output swing is achievable?
Yes, the TLV314IDBVT is fully specified and tested for operation from 1.8 V single supply. Under 10 kΩ load, its rail-to-rail output swings to within 5 mV of both V+ and V–, delivering >99% of the available voltage range - critical for maximizing resolution in 1.8 V–powered microcontrollers and ADCs. This performance is confirmed in Figure 7 and Section 7.7 of the TLV314IDBVT datasheet.
