Texas Instruments TLV9052IDSGR

Overview

TLV9052IDSGR 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 photodiode amplification, low-side current sensing, and sensor signal conditioning where precision, speed, and power efficiency are critical.

For engineers reviewing the TLV9052IDSGR datasheet, TLV9052IDSGR pinout, TLV9052IDSGR application, or TLV9052IDSGR equivalent, this page provides verified electrical specifications, WSON-8 package details, dual-channel functional context, and validated alternative options for industrial and embedded analog front-end designs.

Technical Context

The TLV9052IDSGR implements a CMOS input stage with 2pA typical input bias current and 15nV/√Hz input voltage noise density at 10kHz. Its unity-gain stable architecture supports capacitive loads up to 150pF without external compensation, and its RFI/EMI filtering suppresses high-frequency interference in noisy environments.

Designed for single-supply operation down to 1.8V, it maintains rail-to-rail input common-mode range (V– – 0.1V to V+ + 0.1V) and output swing within 16mV of rails (at 10kΩ load, 5.5V supply), enabling full dynamic range utilization in battery-powered and low-voltage control systems.

FAQ

What is the maximum capacitive load the TLV9052IDSGR can drive while maintaining stability?

The TLV9052IDSGR is specified to drive up to 150pF capacitive load while remaining unity-gain stable, with phase margin ≥60°. Its resistive open-loop output impedance simplifies stabilization with larger loads, and typical phase margin remains >40° even at 300pF. For loads exceeding 150pF, external series resistance at the output is recommended to ensure robustness in production environments.

Does the TLV9052IDSGR support true rail-to-rail input common-mode range?

Yes, the TLV9052IDSGR supports a rail-to-rail input common-mode voltage range from (V–) – 0.1V to (V+) + 0.1V across its full operating temperature range (–40°C to 125°C). This allows direct interfacing with signals referenced to ground or V+ in single-supply configurations without external bias networks.

What is the shutdown capability of the TLV9052IDSGR?

The TLV9052IDSGR does not include a shutdown feature; only the TLV9052S variants (e.g., TLV9052SDGS) offer shutdown pins. The TLV9052IDSGR operates continuously when powered and draws 330µA per channel. For power-gated applications, external enable circuitry or selection of the TLV9052S family is required.

How does the TLV9052IDSGR perform in terms of input offset voltage drift over temperature?

The TLV9052IDSGR exhibits ±0.5µV/°C typical input offset voltage drift over –40°C to +125°C, resulting in ≤125µV total drift across the full range. This low drift, combined with ±0.33mV initial offset, ensures minimal calibration burden in precision measurement systems such as current shunt monitors and sensor front-ends.

Is the TLV9052IDSGR compatible with standard PCB assembly processes including reflow and cleaning?

Yes, the TLV9052IDSGR in WSON-8 (DSG) package is qualified for standard lead-free reflow profiles (J-STD-020) and withstands aqueous and solvent-based cleaning processes. Its exposed thermal pad requires proper stencil design and solder paste volume to ensure reliable thermal and mechanical attachment to the PCB ground plane.
