Texas Instruments TLV313IDBVT

Overview

TLV313IDBVT from Texas Instruments is a single-channel, rail-to-rail input/output precision operational amplifier optimized for cost-sensitive, low-power 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 TLV313IDBVT datasheet, TLV313IDBVT pinout, TLV313IDBVT application, or TLV313IDBVT equivalent, this page provides verified specifications, validated SOT23-5 package mapping, confirmed rail-to-rail I/O behavior across –40°C to +125°C, and real-world design implications of its 1-pA input bias current and integrated RF/EMI filter.

Technical Context

The TLV313IDBVT employs a complementary differential input stage (N- and P-channel pairs) enabling rail-to-rail common-mode input range extending 200 mV beyond both supply rails - with a defined transition region where both pairs conduct. Its class AB output stage achieves full rail-to-rail swing, delivering ≤5 mV from rails into 100-kΩ loads at 25°C.

It is unity-gain stable with capacitive loads up to 1 nF and includes an internal low-pass EMI filter on input pins. PSRR (74–90 dB) and CMRR (64–85 dB) are specified over temperature and supply voltage, with degradation explicitly documented within the input transition region.

FAQ

What is the maximum capacitive load the TLV313IDBVT can drive while remaining stable?

The TLV313IDBVT is unity-gain stable with pure capacitive loads up to 1 nF. For larger loads (e.g., >100 nF), stability can be maintained by adding a 10–20 Ω series resistor between the output and the capacitor. This technique reduces ringing but introduces a small gain error due to voltage division with parallel load resistance. TLV313IDBVT's internal architecture avoids need for external compensation in most standard buffer configurations.

Does TLV313IDBVT support true single-supply operation with rail-to-rail input?

Yes. TLV313IDBVT supports true single-supply operation from 1.8 V to 5.5 V, with input common-mode voltage range extending from (V–) – 0.2 V to (V+) + 0.2 V - meaning it accepts inputs 200 mV below ground and 200 mV above V+ in single-supply configurations. This eliminates the need for input biasing networks in sensor interfaces powered from 3.3 V or 5 V rails.

How does the TLV313IDBVT's EMI filter affect its AC performance?

The integrated RF/EMI filter on TLV313IDBVT's input pins attenuates high-frequency interference (e.g., GSM bursts) without degrading DC accuracy or low-frequency gain. It does not impact bandwidth, slew rate, or noise performance below 1 MHz - verified by flat CMRR/PSRR curves up to 100 kHz in the datasheet. TLV313IDBVT maintains full 1-MHz GBW and 26 nV/√Hz noise density while rejecting conducted EMI that would otherwise cause offset shifts.

What is the output voltage swing capability of TLV313IDBVT at 3.3 V supply?

At VS = 3.3 V and TA = 25°C, TLV313IDBVT delivers output swing to within 5 mV of each rail into 100-kΩ loads, and to within 75 mV of each rail into 2-kΩ loads. This rail-to-rail output behavior is maintained across the full –40°C to +125°C temperature range, with minimal degradation - enabling accurate signal representation in 3.3-V microcontroller ADC interfaces without external level-shifting.

Is TLV313IDBVT pin-compatible with other SOT23-5 op amps like MCP6001 or TS321?

No. TLV313IDBVT uses TI's standard SOT23-5 pinout (Pin 1 = OUT, Pin 2 = V–, Pin 3 = +IN, Pin 4 = –IN, Pin 5 = V+), which differs from Microchip's MCP6001 (Pin 1 = OUT, Pin 2 = –IN, Pin 3 = +IN, Pin 4 = V–, Pin 5 = V+) and ST's TS321 (Pin 1 = OUT, Pin 2 = –IN, Pin 3 = +IN, Pin 4 = V–, Pin 5 = V+). Direct replacement requires PCB layout revision. TLV313IDBVT's pinout matches TI's own TLV6001 and OPA313 families.
