Texas Instruments TLV9054SIRTER

Overview

TLV9054SIRTER from Texas Instruments is a quad-channel, rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It delivers 5MHz unity-gain bandwidth, 15V/µs slew rate, ±0.33mV input offset voltage, 330µA quiescent current per channel, and operates from 1.8V to 6.0V supply. It is used in precision sensor signal conditioning and low-side current sensing circuits where high speed and low power coexist.

For engineers reviewing the TLV9054SIRTER datasheet, TLV9054SIRTER pinout, TLV9054SIRTER application, or TLV9054SIRTER equivalent, key selection criteria include shutdown functionality (dual-pair control), WQFN-16 package thermal performance (R_θJA = 65.5°C/W), rail-to-rail output swing within 16mV of rails (at 5.5V, 10kΩ), and guaranteed operation across –40°C to +125°C.

Technical Context

The TLV9054SIRTER integrates four independent CMOS op amps with internal RFI/EMI filtering and unity-gain stability up to 150pF capacitive load. Its architecture supports single-supply operation with common-mode input range extending 0.1V beyond both rails and output swing to within 16mV of each rail at 5.5V.

It features dual independent shutdown controls (SHDN12 and SHDN34) enabling selective channel disabling with 6µs turn-off and 35µs full-enable timing. Input bias current remains ultra-low (±2pA typ) across temperature, and open-loop gain exceeds 104dB at 5.5V, supporting high-precision closed-loop configurations.

FAQ

What is the maximum capacitive load the TLV9054SIRTER can drive while maintaining stability?

The TLV9054SIRTER is unity-gain stable up to 150pF capacitive load, as confirmed in the datasheet's Phase Margin vs Capacitive Load plot (Figure 6-17). At 150pF, phase margin remains ≥60°, ensuring robust step response without peaking or oscillation. For loads exceeding 150pF, external isolation resistance (e.g., 10–50Ω in series with output) is recommended to preserve stability. This capability simplifies interface with ADC input capacitors and long PCB traces in TLV9054SIRTER-based designs.

Does the TLV9054SIRTER support true rail-to-rail input with 1.8V supply?

Yes, the TLV9054SIRTER supports rail-to-rail input operation down to 1.8V supply, with common-mode voltage range specified as (V−) − 0.1V to (V+) + 0.1V across the full operating temperature range. At 1.8V, this means inputs function from −0.1V to +1.9V-enabling direct interfacing with sensors whose outputs swing near ground or VDD. This is verified in Section 6.7 (VCM specification) and Figure 6-4 (Offset Voltage vs Common-Mode Voltage) of the TLV9054SIRTER datasheet.

How does shutdown mode affect output state in the TLV9054SIRTER?

In shutdown mode (SHDN12 or SHDN34 pulled low), the corresponding amplifier pair enters high-impedance output state-neither sourcing nor sinking current. The output floats electrically, decoupling the amplifier from downstream circuitry. This behavior prevents loading or back-driving of connected stages (e.g., ADC inputs or filter networks) and is explicitly documented in Section 7.4 (Device Functional Modes) and Table 6-7 (Z_SHDN = 10 GΩ || 2 pF). No pull-up/down is required on TLV9054SIRTER outputs during shutdown.

What is the typical input offset voltage drift of the TLV9054SIRTER over temperature?

According to the TLV9054SIRTER datasheet (Section 6.7), the typical input offset voltage drift is ±0.5µV/°C over the full –40°C to +125°C range. This low drift-validated across production lots (Figure 6-2)-ensures minimal baseline shift in precision DC-coupled paths such as strain gauge amplifiers or thermistor linearization circuits. The value is measured under standard conditions (VS = 5V) and applies uniformly to all four channels in the TLV9054SIRTER device.

Can the TLV9054SIRTER operate with asymmetric supplies, e.g., V+ = 5V and V− = –2V?

No-the TLV9054SIRTER is specified only for total supply voltage (V+ − V−) between 1.8V and 6.0V, with absolute maximum ratings limiting V+ to 7V and V− to –0.5V relative to V+. Asymmetric supplies like V+ = 5V and V− = –2V yield 7V total, exceeding the 6.0V recommended maximum and risking reliability degradation. The device is optimized for single-supply (e.g., 3.3V or 5V with V− = GND) or symmetric dual-supply (e.g., ±2.5V) use cases within the 1.8–6.0V window. This constraint is defined in Sections 6.1 and 6.3 of the TLV9054SIRTER datasheet.
