Texas Instruments TLV271IDBVT

Overview

TLV271IDBVT from Texas Instruments is a single-channel, rail-to-rail output operational amplifier optimized for low-power, wide-bandwidth signal conditioning in battery-powered and industrial systems. It delivers 3-MHz unity-gain bandwidth, 2.4 V/µs slew rate, 550 µA supply current per channel, 39 nV/√Hz input voltage noise, and operates from 2.7 V to 16 V over −40°C to +125°C. It is used in smoke detectors and power banks where precision, low quiescent current, and rail-to-rail swing are critical.

For engineers reviewing the TLV271IDBVT datasheet, TLV271IDBVT pinout, TLV271IDBVT application, or TLV271IDBVT equivalent, key selection criteria include its CMOS-input architecture (1 pA bias current), rail-to-rail output capability down to 100 mV from rails at 1 mA load, −40°C to +125°C industrial temperature rating, and SOT-23-5 ultrasmall package compatibility with space-constrained PCB layouts.

Technical Context

The TLV271IDBVT employs a CMOS input stage enabling ultra-low input bias current (1 pA typical) and high input impedance, making it suitable for high-impedance sensor interfaces such as thermistors and photodiodes. Its rail-to-rail output stage uses complementary push-pull circuitry to achieve output swing within 100 mV of both supply rails under 1 mA load.

It features a stable unity-gain compensated design with 65° phase margin into 10 pF capacitive load, and supports operation on single supplies (2.7–16 V) or split supplies (±1.35 V to ±8 V). The device exhibits 70 dB PSRR and 58–85 dB CMRR depending on supply voltage and common-mode range.

FAQ

What is the maximum supply voltage for TLV271IDBVT?

The absolute maximum supply voltage for TLV271IDBVT is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation above 16 V risks permanent damage. At 16 V, the device supports ±8-V split-supply configurations and is compatible with 12-V auxiliary rails in solar inverters and industrial PLCs. Always observe thermal limits: R_θJA = 221.7°C/W in SOT-23 limits power dissipation to ~22 mW at 70°C ambient.

Does TLV271IDBVT support rail-to-rail input?

No, TLV271IDBVT does not support rail-to-rail input; it features rail-to-rail *output* only. The input common-mode voltage range is specified as 0 V to V_DD − 1.35 V. For example, at V_DD = 3.3 V, the usable input range is 0 V to 1.95 V. This limitation requires careful biasing in single-supply applications-such as using a Thevenin-equivalent divider to center the input signal within the valid range.

What is the typical input offset voltage of TLV271IDBVT?

The typical input offset voltage of TLV271IDBVT is 5 mV at 25°C, with a maximum of 7 mV over the full −40°C to +125°C industrial temperature range. Offset voltage drift is 2 µV/°C, contributing ≤0.25 mV additional error across a 125°C span. For precision applications, external trimming or auto-zero architectures may be needed-though the 1 pA input bias current helps minimize resistor-induced offset errors in high-gain configurations.

Can TLV271IDBVT drive capacitive loads directly?

TLV271IDBVT can drive ≤10 pF capacitive loads stably without external compensation. For loads >10 pF (e.g., long PCB traces or ADC input capacitance), TI recommends adding a series resistor (R_NULL ≥ 20 Ω) between the TLV271IDBVT output and the load to maintain ≥65° phase margin and prevent ringing. This isolation technique preserves stability without degrading DC accuracy, as R_NULL does not affect closed-loop gain in unity-gain buffer configurations.

Is TLV271IDBVT pin-compatible with other SOT-23 op-amps?

TLV271IDBVT follows the standard 5-pin SOT-23 op-amp pinout (OUT, GND, IN+, IN−, VDD), making it mechanically and functionally compatible with industry-standard single op-amps like LMV321, MCP6001, and TLV341. However, electrical differences-such as bandwidth (3 MHz), supply current (550 µA), and input stage (CMOS vs. bipolar)-require validation in the target circuit. No redesign is needed for footprint or basic connection, but loop stability and noise performance must be rechecked.
