Product details
Overview
TLV9052QPWRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 qualified CMOS operational amplifier optimized for automotive powertrain and battery management systems. It delivers 5MHz unity-gain bandwidth, 15V/µs slew rate, rail-to-rail input/output swing, ±0.33mV max input offset voltage, and 330µA per amplifier quiescent current at 5.5V supply - enabling high-speed signal conditioning in HEV/EV DC/DC converters and motor control feedback loops.
For engineers reviewing the TLV9052QPWRQ1 datasheet, TLV9052QPWRQ1 pinout, TLV9052QPWRQ1 application, or TLV9052QPWRQ1 equivalent, this page provides verified technical context, package-specific pin functions, automotive-grade performance boundaries, and validated alternative options for cost- and space-constrained designs operating from 1.8V to 6.0V.
Technical Context
The TLV9052QPWRQ1 implements a complementary-input-stage architecture enabling rail-to-rail common-mode operation (V– – 0.1V to V+ + 0.1V) across its full 1.8V–6.0V supply range. Its class AB output stage achieves 16mV rail-to-rail swing into 10kΩ loads while maintaining 60° phase margin and unity-gain stability with up to 150pF capacitive load.
It integrates on-die RFI/EMI filtering, delivering ≥53.1dB EMIRR at 900MHz and ≥70.0dB at 2.4GHz - critical for noise immunity in electric vehicle power electronics. Input bias current remains ultra-low (±2pA typ) and offset drift is tightly controlled (±0.5µV/°C), supporting precision current sensing and closed-loop control over –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8V to 6.0V - supports direct connection to 3.3V or 5V automotive rails and low-voltage battery monitoring circuits |
| Unity-Gain Bandwidth | 5MHz - enables stable amplification of fast transients in motor phase current feedback and BMS cell voltage sampling |
| Slew Rate | 15V/µs - ensures minimal distortion in high-slew applications like gate driver biasing and PWM reconstruction |
| Input Offset Voltage | ±0.33mV (max at 25°C) - reduces gain error in precision shunt-based current measurement without calibration |
| Quiescent Current | 330µA per amplifier - allows dual-channel operation in always-on vehicle subsystems without excessive standby power draw |
| Input Bias Current | ±2pA (typ) - minimizes voltage error in high-impedance sensor interfaces such as thermistor or potentiometer networks |
| EMI Rejection Ratio | ≥70.0dB at 2.4GHz - suppresses interference from Bluetooth/Wi-Fi modules co-located on EV control boards |
Pinout & Package
TSSOP-8 (PW) package: 3.00mm × 6.40mm body, 0.65mm pitch, surface-mount, moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1– (Pin 2) | Inverting input, channel 1 | Accepts feedback signal in inverting amplifier configurations; compatible with single-supply rail-to-rail common-mode range |
| IN1+ (Pin 3) | Noninverting input, channel 1 | Receives reference or sensor signal; operates down to V– – 0.1V and up to V+ + 0.1V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, rail-to-rail, automotive op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV932QDRQ1 | Lower slew rate (1.5V/µs), wider offset range (±3.5mV), same AEC-Q100 Grade 1, SOIC-8 only | Better suited for low-bandwidth sensor buffering; insufficient for fast current-loop feedback | Select when cost sensitivity outweighs speed requirements and SOIC-8 footprint is acceptable |
| TSV912AQDR | Higher quiescent current (820µA), lower EMI rejection (no integrated filter), same 5MHz GBW, VSSOP-8 only | Lacks EMI hardening for noisy powertrain environments; requires external filtering for robustness | Choose only if board-level EMI mitigation is already implemented and higher IQ is tolerable |
Compared with LMV932QDRQ1 and TSV912AQDR, TLV9052QPWRQ1 uniquely combines high-speed performance (15V/µs), ultra-low IQ (330µA), integrated EMI filtering, and TSSOP-8 packaging - making it the optimal choice for space-constrained, noise-immune, battery-efficient automotive power control loops.

FAQ
What is the maximum capacitive load the TLV9052QPWRQ1 can drive while remaining stable?
The TLV9052QPWRQ1 is specified for unity-gain stability with up to 150pF capacitive load, as confirmed in the datasheet's Phase Margin vs Capacitive Load plot (Figure 5-17). Driving larger loads may reduce phase margin below 60°, risking oscillation. For loads exceeding 150pF, external isolation resistance or compensation is required. TLV9052QPWRQ1 maintains stability without added components under this limit.
Does TLV9052QPWRQ1 support true rail-to-rail input at 1.8V supply?
Yes - the TLV9052QPWRQ1 guarantees rail-to-rail input operation from V– – 0.1V to V+ + 0.1V across its entire 1.8V–6.0V supply range, including at 1.8V. This is enabled by its complementary N/P-channel input stage, allowing use in ultra-low-voltage automotive subsystems such as 1.8V microcontroller sensor interfaces. TLV9052QPWRQ1 maintains this specification over –40°C to +125°C.
Is TLV9052QPWRQ1 pin-compatible with other devices in the TLV905x-Q1 family?
No - TLV9052QPWRQ1 (dual-channel, TSSOP-8) has a different pinout than TLV9051-Q1 (single, SOT-23/SC70) and TLV9054-Q1 (quad, SOIC/TSSOP-14). Pin assignments for IN1±, IN2±, OUT1/OUT2, and supply terminals are unique to the dual-channel 8-pin configuration. TLV9052QPWRQ1 requires its own layout; no mechanical or electrical drop-in replacement exists within the family.
What is the typical EMI rejection performance of TLV9052QPWRQ1 at 2.4GHz?
TLV9052QPWRQ1 delivers 70.0dB electromagnetic interference rejection ratio (EMIRR) at 2.4GHz, as measured at the noninverting input per the datasheet's Table 6-1. This performance is achieved via integrated on-die RFI/EMI filtering, eliminating the need for external ferrite beads or RC networks in Bluetooth/Wi-Fi–dense automotive environments. TLV9052QPWRQ1 maintains this rating across temperature and supply voltage variations.
Can TLV9052QPWRQ1 operate from a single 3.3V supply in automotive applications?
Yes - TLV9052QPWRQ1 is fully specified for single-supply operation from 1.8V to 6.0V, including 3.3V. Its rail-to-rail input/output, 330µA quiescent current, and AEC-Q100 Grade 1 qualification make it ideal for 3.3V domains such as ADAS camera modules, infotainment power management, and body control units. TLV9052QPWRQ1 meets all electrical and thermal specifications at 3.3V across –40°C to +125°C.
