Product details
Overview
TLV9052SIRUGR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier with shutdown control, designed for low-voltage, high-speed signal conditioning. 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 TLV9052SIRUGR datasheet, TLV9052SIRUGR pinout, TLV9052SIRUGR application, or TLV9052SIRUGR equivalent, key selection criteria include dual-channel shutdown timing (tON = 35µs full, tOFF = 6µs), 10-pin X2QFN (1.5mm × 2mm) thermal performance (RθJA = 197.2°C/W), and guaranteed rail-to-rail operation across –40°C to +125°C.
Technical Context
The TLV9052SIRUGR integrates two independent CMOS op-amp cores with individual shutdown pins (SHDN1 and SHDN2), enabling selective channel disablement without affecting the other. Its internal RFI/EMI filter and phase-reversal immunity support robust operation in noisy industrial environments.
It features unity-gain stability with capacitive-load drive capability up to 150pF and resistive open-loop output impedance that simplifies compensation for higher loads. The device uses a scalable CMOS process optimized for cost-sensitive, low-power applications requiring fast settling (0.75µs to 0.1%) and low broadband noise (15nV/√Hz at 10kHz).

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9062DR | Higher 10MHz GBW, 3.5V/µs slew rate, no shutdown; 360µA IQ; SOIC-8 | Lacks channel disable; better for wideband filtering but less suitable for intermittent sensing | Choose when bandwidth >5MHz is required and shutdown is unnecessary |

FAQ
What is the maximum capacitive load the TLV9052SIRUGR can drive while maintaining stability?
The TLV9052SIRUGR is specified to drive up to 150pF with guaranteed phase margin ≥60° and unity-gain stability. Its resistive open-loop output impedance simplifies compensation for larger loads, and typical phase margin remains >40° even at 300pF. For designs exceeding 150pF, external series resistance at the output is recommended to ensure robust transient response in TLV9052SIRUGR-based circuits.
Does the TLV9052SIRUGR support true rail-to-rail input common-mode voltage?
Yes, the TLV9052SIRUGR supports rail-to-rail input common-mode voltage from (V–) – 0.1V to (V+) + 0.1V across its full operating temperature range (–40°C to +125°C). This allows direct interfacing with grounded shunt resistors and sensors referenced to either supply rail-critical for low-side current sensing and single-supply photodiode amplifiers using TLV9052SIRUGR.
How does the shutdown function behave in the TLV9052SIRUGR?
The TLV9052SIRUGR provides independent active-high shutdown pins (SHDN1 and SHDN2). When pulled below (V–) + 0.2V, the corresponding amplifier enters ultra-low-power state (<1µA total IQ per disabled channel). Enable time is 35µs for full startup (both channels) and 10µs for partial (one channel), with disable time of 6µs. Each pin draws only 6.5nA bias current, minimizing impact on controlling logic in TLV9052SIRUGR applications.
What is the typical input offset voltage drift of the TLV9052SIRUGR over temperature?
The TLV9052SIRUGR has a typical input offset voltage drift of ±0.5µV/°C over the full –40°C to +125°C range. Production data shows >90% of units exhibit drift ≤1.2µV/°C, ensuring stable DC accuracy in temperature-varying environments like motor control feedback loops and HVAC sensor interfaces using TLV9052SIRUGR.
Can the TLV9052SIRUGR operate from a 1.8V single supply?
Yes, the TLV9052SIRUGR is fully specified for operation from 1.8V to 6.0V total supply voltage (V+ – V–). At 1.8V, it maintains rail-to-rail input/output swing, 5MHz gain-bandwidth product, and 15V/µs slew rate-enabling compatibility with modern ultra-low-voltage MCUs and battery-powered IoT edge nodes where TLV9052SIRUGR serves as front-end signal conditioner.
