Texas Instruments TLV27L1IDBVT

Overview

TLV27L1IDBVT from Texas Instruments is a single-channel micropower rail-to-rail output operational amplifier designed for ultra-low-power sensor signal conditioning and battery-powered instrumentation. It delivers 160 kHz gain-bandwidth, 0.1 V/μs slew rate, 7 μA supply current per channel, 89 nV/√Hz input noise, and operates from 2.7 V to 16 V over −40°C to +125°C - enabling use in portable medical devices and industrial power monitoring.

For engineers reviewing the TLV27L1IDBVT datasheet, TLV27L1IDBVT pinout, TLV27L1IDBVT application, or TLV27L1IDBVT equivalent, key selection criteria include its SOT-23-5 package, 1 pA input bias current, rail-to-rail output swing down to 2.7 V supply, and guaranteed performance across extended temperature range without sacrificing quiescent power.

Technical Context

The TLV27L1IDBVT employs BiMOS input stage architecture to achieve 1 pA typical input bias current while maintaining rail-to-rail output swing via complementary bipolar output transistors. Its 160 kHz unity-gain bandwidth is optimized for low-frequency precision sensing rather than high-speed signal processing.

It features a wide input common-mode voltage range (−0.2 V to VS+1.2 V), 71 dB minimum CMRR at 25°C, and 74 dB PSRR - supporting accurate DC-coupled amplification in noisy industrial environments where supply rejection and common-mode immunity are critical.

FAQ

What is the maximum supply voltage for TLV27L1IDBVT?

The absolute maximum supply voltage for TLV27L1IDBVT is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Exceeding 16.5 V risks permanent damage. At 16 V, the device supports ±8-V dual-supply configurations while maintaining rail-to-rail output swing and 7 μA quiescent current - a key advantage over older TLC27Lx variants.

Does TLV27L1IDBVT support rail-to-rail input?

No, TLV27L1IDBVT does not support rail-to-rail input. Its input common-mode voltage range is specified as −0.2 V to VS−1.2 V - meaning the inputs cannot operate within 1.2 V of the positive rail. However, it does provide true rail-to-rail output swing, delivering voltages within 50 mV of both supply rails under load. This makes TLV27L1IDBVT ideal for output-buffering applications where input range is less constrained.

What is the input offset voltage specification for TLV27L1IDBVT?

The TLV27L1IDBVT has a maximum input offset voltage of 7 mV across the full −40°C to +125°C temperature range, with a typical value of 5 mV at 25°C. This is identical to the TLC27LxA variant, enabling direct migration in precision DC-coupled circuits. The offset voltage drift is 1.1 μV/°C, contributing to stable baseline performance in thermally varying environments like automotive engine compartments.

Can TLV27L1IDBVT drive capacitive loads?

TLV27L1IDBVT can drive moderate capacitive loads, but stability must be verified per application. Phase margin drops to 62° at 25°C with 50 pF load and 100-kΩ resistive load; larger capacitive loads risk peaking or oscillation. TI recommends using a series resistor (e.g., 10–100 Ω) between the output and capacitive load, or adding a small isolation capacitor in the feedback path for critical timing applications. Always validate loop stability with actual PCB parasitics.

Is TLV27L1IDBVT pin-compatible with other SOT-23-5 op-amps?

TLV27L1IDBVT follows standard SOT-23-5 pinout (IN−, IN+, GND, VDD, OUT), matching industry conventions used by TI's TLVx38x and OPAx34x families. However, it is not a drop-in replacement for all SOT-23-5 op-amps due to differences in input stage architecture, bias current, and output drive capability. For example, substituting TLV27L1IDBVT for an OPA349 requires verifying that the higher 1 pA bias current and lower 160 kHz GBW meet system requirements.
