Texas Instruments TLV9052IDR

Overview

TLV9052IDR from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for low-voltage, high-speed signal conditioning in cost-sensitive systems. 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 current shunt monitoring for DC motor control and photodiode amplification.

For engineers reviewing the TLV9052IDR datasheet, TLV9052IDR pinout, TLV9052IDR application, or TLV9052IDR equivalent, key selection criteria include its rail-to-rail I/O capability at 1.8V, low-noise (15nV/√Hz) performance, EMI/RFI filtering, unity-gain stability with up to 150pF capacitive load, and extended –40°C to +125°C temperature range.

Technical Context

The TLV9052IDR employs a CMOS input stage enabling ultra-low input bias current (2pA typ) and rail-to-rail common-mode input range extending 100mV beyond rails. Its high slew rate and 5MHz gain-bandwidth product support fast settling (0.75µs to 0.1%) in single-supply sensor interfaces without phase reversal under overdrive.

Designed for robust operation in noisy environments, it integrates internal RFI/EMI filters and features resistive open-loop output impedance that simplifies stabilization with heavy capacitive loads-critical for driving ADC inputs or long traces in industrial sensing nodes.

Key Specifications

Pinout & Package

TLV9052IDR is packaged in an 8-pin SOIC (D) package measuring 4.9mm × 6.0mm with standard lead pitch and exposed pad not present. Pin functions are validated per TI SBOS942J Rev F (Feb 2024).

FAQ

What is the maximum capacitive load the TLV9052IDR can drive while remaining stable?

The TLV9052IDR is specified to remain unity-gain stable with up to 150pF capacitive load, as confirmed in TI's SBOS942J datasheet Figure 6-17 (Phase Margin vs Capacitive Load). This enables direct connection to typical 12–16-bit SAR ADC inputs without isolation resistors, reducing signal path error and board space. Exceeding 150pF may reduce phase margin below 60°, risking oscillation in G = +1 configurations.

Does the TLV9052IDR support true rail-to-rail input at 1.8V supply?

Yes, the TLV9052IDR supports rail-to-rail input common-mode range from (V–) – 0.1V to (V+) + 0.1V across its full 1.8V–6.0V supply range, including at 1.8V. This is verified in Section 6.7 (Input Voltage Range, VCM) of the SBOS942J datasheet. At 1.8V, inputs operate from –0.1V to +1.9V, enabling compatibility with 0–1.8V sensor outputs and reference voltages.

What is the typical input offset voltage drift over temperature for TLV9052IDR?

The TLV9052IDR exhibits ±0.5µV/°C typical input offset voltage drift over –40°C to +125°C, as specified in the "dVOS/dT" parameter (Section 6.7). This low drift ensures minimal calibration burden in wide-temperature applications like HVAC control-contributing to <±2mV total offset error across the full range, critical for precision shunt-based current measurement.

Can TLV9052IDR be used in single-supply photodiode transimpedance amplifier circuits?

Yes, TLV9052IDR is well-suited for single-supply photodiode TIA designs due to its 2pA typical input bias current, 15nV/√Hz input voltage noise, rail-to-rail input (down to V– – 0.1V), and internal EMI filtering. These features minimize dark current error, preserve SNR in low-light conditions, and reject switching noise from nearby DC/DC converters-key advantages over general-purpose op-amps like LM358.

Is the TLV9052IDR pin-compatible with other devices in the TLV905x family?

No, TLV9052IDR (8-pin SOIC) is not pin-compatible with TLV9051 (5-pin SOT-23/SC70) or TLV9054 (14/16-pin SOIC/TSSOP/WQFN). Pinouts differ fundamentally: TLV9052IDR uses Pins 1–8 for OUT1, IN1–, IN1+, V–, IN2+, IN2–, OUT2, V+, whereas TLV9051 has only 5 pins and TLV9054 allocates 14–16 pins across four channels. Board layout must be dedicated to TLV9052IDR's SOIC-8 footprint.
