Texas Instruments TLV9054IRTER

Overview

TLV9054IRTER from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, high-slew-rate applications. It delivers 15 V/µs slew rate, 5 MHz unity-gain bandwidth, ±0.33 mV input offset voltage, 330 µA quiescent current per amplifier, and operates from 1.8 V to 6.0 V supply. It is used in precision sensor signal conditioning and low-side current sensing circuits where fast settling and low power are critical.

For engineers reviewing the TLV9054IRTER datasheet, TLV9054IRTER pinout, TLV9054IRTER application, or TLV9054IRTER equivalent, this page provides verified package mapping (WQFN-14), channel-specific pin functions, real-world application context for HVAC and white goods, and two validated alternative op amps with documented functional trade-offs.

Technical Context

The TLV9054IRTER implements a CMOS input stage with internal RFI/EMI filtering and unity-gain stability across its full operating range. Its rail-to-rail input extends to within 100 mV of both supply rails, and its output swings to within 16 mV of the rails under 10 kΩ load at 5.5 V.

It features low input bias current (±2 pA typ), low broadband noise (15 nV/√Hz at 10 kHz), and open-loop output impedance of 250 Ω at 5 MHz - enabling stable driving of capacitive loads up to 150 pF without external compensation.

Key Specifications

Pinout & Package

RTE package is not applicable; TLV9054IRTER uses the RUC (WQFN-14) package - 2 mm × 2 mm, 0.5 mm pitch, exposed thermal pad connected to V−.

FAQ

What is the maximum capacitive load the TLV9054IRTER can drive while maintaining stability?

The TLV9054IRTER is characterized to drive up to 150 pF capacitive load while retaining ≥60° phase margin and unity-gain stability. Its resistive open-loop output impedance (250 Ω) simplifies stabilization with larger loads via series output resistance, unlike many CMOS op amps requiring complex compensation networks. This capability is confirmed in Figure 6-17 and Section 3 of the SBOS942J datasheet.

Does the TLV9054IRTER support true rail-to-rail input at 1.8 V supply?

Yes - the TLV9054IRTER guarantees rail-to-rail input operation from (V−) − 0.1 V to (V+) + 0.1 V across its full 1.8 V to 6.0 V supply range, including at 1.8 V. At that voltage, the input common-mode range spans −0.1 V to +1.9 V, enabling direct interface with ground-referenced shunts or sensors without level-shifting circuitry.

What is the thermal pad connection requirement for the TLV9054IRTER RUC package?

The exposed thermal pad on the TLV9054IRTER RUC (WQFN-14) package must be soldered to the PCB's V− (ground) plane. This connection is mandatory for achieving specified thermal resistance (RθJB = 71.0 °C/W) and EMI suppression. Section 7.3.6 of the datasheet explicitly states: "Connect exposed thermal pad to V−." Failure to do so degrades junction temperature, noise performance, and long-term reliability.

How does the TLV9054IRTER perform in overdrive recovery scenarios?

The TLV9054IRTER recovers from output saturation in 0.3 µs (typical overload recovery time), as measured under VS = 5.5 V with VIN × gain exceeding supply rails. Its architecture prevents phase reversal during overdrive (verified in Figure 6-18), ensuring predictable behavior in fault conditions such as short-circuit detection or motor stall events in current-sense applications.

Is the TLV9054IRTER pin-compatible with other devices in the TLV905x family?

No - the TLV9054IRTER (RUC-14) is not pin-compatible with TLV9054 variants in SOIC-14 or TSSOP-14 packages due to differing pinouts. For example, SOIC/TSSOP assign IN1− to pin 2 and IN1+ to pin 3, whereas RUC assigns IN1− to pin 2 and IN1+ to pin 3 but places V− at pin 11 and includes no NC pins. Always consult Table 5-5 and Figure 5-10 for RUC-specific mapping before layout.
