Texas Instruments TLV9052IPWR

Overview

TLV9052IPWR from Texas Instruments is a dual, rail-to-rail input/output operational amplifier optimized for low-voltage, low-power precision signal conditioning. It delivers 5MHz unity-gain bandwidth, 15V/µs slew rate, ±0.33mV max 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 speed, accuracy, and power efficiency are critical.

For engineers reviewing the TLV9052IPWR datasheet, TLV9052IPWR pinout, TLV9052IPWR application, or TLV9052IPWR equivalent, key selection criteria include its dual-channel SOIC-8 package, rail-to-rail operation at 1.8V, 15V/µs slew rate under 130pF load, and verified performance across –40°C to +125°C industrial temperature range.

Technical Context

The TLV9052IPWR employs a CMOS input stage enabling 2pA typical input bias current and rail-to-rail input common-mode range extending 100mV beyond rails. Its high-speed architecture achieves 5MHz gain-bandwidth product and 60° phase margin at unity gain, ensuring stability with capacitive loads up to 150pF without external compensation.

It features internal RFI/EMI filtering and is free from phase reversal during overdrive. The device uses a resistive open-loop output impedance that simplifies stabilization with higher capacitive loads, and supports single-supply operation down to 1.8V while maintaining full rail-to-rail output swing into 10kΩ.

FAQ

What is the maximum capacitive load the TLV9052IPWR can drive while maintaining stability?

The TLV9052IPWR is characterized for stable operation with up to 150pF capacitive load at unity gain, as confirmed in Figure 6-17 (Phase Margin vs Capacitive Load) and Section 3 of the datasheet. Its resistive open-loop output impedance enables reliable stabilization even beyond this value with minor gain peaking; however, for production designs requiring guaranteed 60° phase margin, 150pF is the validated limit without external compensation.

Does the TLV9052IPWR support true rail-to-rail input common-mode voltage?

Yes, the TLV9052IPWR supports rail-to-rail input common-mode voltage from (V–) – 0.1V to (V+) + 0.1V, as specified in Section 6.3 (Recommended Operating Conditions) and Table 6-7 (Electrical Characteristics). This allows direct interfacing with sensors operating at the supply rails, such as bridge circuits referenced to V+ and V–, without external level-shifting.

What is the typical input bias current of the TLV9052IPWR, and how does it affect high-impedance sensor interfaces?

The TLV9052IPWR has a typical input bias current of 2pA, with a maximum of ±18pA at 25°C and ±525pA over –40°C to +125°C (Section 6.7). At 2pA, it introduces <2µV error across a 1MΩ photodiode leakage path - making it suitable for precision photodiode, piezoelectric, and pH electrode interfaces where bias-induced offset must be minimized.

Can the TLV9052IPWR operate from a single 1.8V supply, and what performance is guaranteed at that voltage?

Yes, the TLV9052IPWR is fully specified from 1.8V to 6.0V supply. At 1.8V, it guarantees 106dB open-loop gain (RL = 10kΩ), 88dB CMRR, 108dB open-loop gain (RL = 2kΩ), and rail-to-rail output swing within 40mV of each rail - enabling functional operation in energy-harvesting and coin-cell-powered systems without performance compromise.

Is the TLV9052IPWR susceptible to phase reversal when inputs exceed the common-mode range?

No, the TLV9052IPWR is explicitly designed to be free from phase reversal under overdrive conditions, as stated in Section 3 (Description) and verified in Figure 6-18 (No Phase Reversal). This eliminates output polarity inversion during transient overload - a critical reliability feature in closed-loop motor control and safety-critical sensor monitoring where unexpected sign flips could cause system faults.
