Texas Instruments TLV9052IDDFR

Overview

TLV9052IDDFR from Texas Instruments is a dual, rail-to-rail input/output operational amplifier optimized for low-voltage, high-speed signal conditioning in cost-sensitive 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 photodiode amplification, low-side current sensing, and sensor signal conditioning where precision, speed, and power efficiency are critical.

For engineers reviewing the TLV9052IDDFR datasheet, TLV9052IDDFR pinout, TLV9052IDDFR application, or TLV9052IDDFR equivalent, key selection criteria include its dual-channel SOT-23-8 package, rail-to-rail operation at 1.8V, 15V/µs slew rate under 130pF load, 15nV/√Hz input voltage noise, and guaranteed performance across –40°C to +125°C.

Technical Context

The TLV9052IDDFR employs a CMOS input stage with 2pA typical input bias current and internal RFI/EMI filtering to maintain stability in noisy environments. Its unity-gain stable architecture supports direct use in gain-of-1 configurations without external compensation.

It features resistive open-loop output impedance enabling robust capacitive-load drive up to 150pF, and exhibits no phase reversal during overdrive - critical for reliable operation in feedback-critical sensor interfaces and active filters.

FAQ

What is the maximum capacitive load the TLV9052IDDFR can drive while maintaining stability?

The TLV9052IDDFR is characterized to drive up to 150pF capacitive load while retaining ≥60° phase margin and stable unity-gain operation. Its resistive open-loop output impedance simplifies compensation for larger loads, and Figure 6-17 in the datasheet confirms stable behavior up to 350pF with minor overshoot. For designs exceeding 150pF, adding a small series resistor (e.g., 10–50Ω) between OUT and the load restores optimal transient response. TLV9052IDDFR's architecture avoids the need for dominant-pole compensation in standard configurations.

Does the TLV9052IDDFR support true rail-to-rail input common-mode range?

Yes - the TLV9052IDDFR supports a common-mode input 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 in single-supply systems (e.g., 0–1.8V inputs on a 1.8V rail) and accommodates overvoltage transients within ±0.1V of the supply rails. The specification is verified per Section 6.7 of the SBOS942J datasheet under recommended operating conditions.

What is the shutdown capability of the TLV9052IDDFR?

The TLV9052IDDFR does not include a shutdown feature - it is the standard dual version (TLV9052), not the shutdown variant (TLV9052S). The DDF package corresponds exclusively to the non-shutdown TLV9052. If low-power disable functionality is required, the pin-compatible TLV9052SDR (VSSOP-10) or TLV9052SRUGR (X2QFN-10) should be selected instead. TLV9052IDDFR draws 330µA per channel continuously and cannot be externally disabled.

How does the TLV9052IDDFR perform in single-supply 1.8V operation?

TLV9052IDDFR is fully specified and tested down to 1.8V supply, delivering 5MHz GBW, 15V/µs slew rate, and rail-to-rail input/output swing - all while maintaining ±0.33mV offset and 15nV/√Hz noise. At 1.8V, output swing reaches within 16mV of each rail into 10kΩ, and CMRR remains ≥88dB. Its low-voltage optimization makes it ideal for energy-efficient portable and IoT sensor nodes where traditional 3.3V op amps fail to meet bandwidth or headroom requirements. TLV9052IDDFR's performance is validated per Table 6-7 in SBOS942J.

Is the TLV9052IDDFR RoHS-compliant and halogen-free?

Yes - TLV9052IDDFR is RoHS-compliant and halogen-free per Texas Instruments' official packaging information (SPRT639B, "TLV9051, TLV9052, TLV9054 Packaging Information"). It uses lead-free NiPdAu terminal finish and green molding compound. The device meets JEDEC J-STD-609 Category 1 for halogen content (<900ppm Br, <900ppm Cl, total ≤1500ppm) and complies with EU Directive 2011/65/EU.
