Product details
Overview
TLV2464AQPWRQ1 from Texas Instruments is a quad-channel, automotive-grade rail-to-rail input/output operational amplifier with shutdown functionality, 6.4 MHz gain-bandwidth product, 1.6 V/μs slew rate, ±80-mA output drive, and 500 μA/channel supply current. It operates from 2.7 V to 6 V and is qualified per AEC-Q100 Grade 1 (–40°C to +125°C) for use in battery management systems and lighting modules.
For engineers reviewing the TLV2464AQPWRQ1 datasheet, TLV2464AQPWRQ1 pinout, TLV2464AQPWRQ1 application, or TLV2464AQPWRQ1 equivalent, key selection considerations include its quad-channel TSSOP-14 package with individual channel shutdown pins, rail-to-rail output swing down to 100 mV from rails at ±40 mA, and low 11 nV/√Hz input noise voltage at 1 kHz - critical for precision analog front-ends in HEV/EV powertrain monitoring.
Technical Context
The TLV2464AQPWRQ1 integrates four independent amplifiers in a single monolithic IC, each featuring complementary input stage architecture enabling rail-to-rail common-mode input range (–0.2 V to VDD + 0.2 V) and rail-to-rail output swing. Its internal shutdown logic accepts TTL-compatible control signals (VIH ≥ 2 V, VIL ≤ 0.7 V) per channel, placing unused amplifiers into 0.3 μA ultra-low-current state while maintaining high-impedance outputs.
Designed for low-voltage, high-dynamic-range signal conditioning, it delivers 6.4 MHz bandwidth and 92 dB typical CMRR at 5 V supply, with closed-loop output impedance of 29 Ω at 100 kHz. The device supports stable operation with capacitive loads up to 160 pF and exhibits 45° phase margin under unity-gain conditions with 10 kΩ load and 160 pF capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.4 MHz - enables stable unity-gain buffer or gain-of-10 amplification up to ~640 kHz without peaking. |
| Slew rate | 1.6 V/μs - supports clean 100-kHz, 1-VPP sine wave reproduction with <0.01% THD+N at AV = 1. |
| Output drive | ±80 mA - drives 62 Ω loads directly (e.g., 5 V into 62 Ω), eliminating need for external buffers in lighting PWM dimming circuits. |
| Supply current per channel | 500 μA - draws only 2 mA total quiescent current for all four channels, ideal for always-on vehicle subsystems. |
| Input offset voltage | 150 μV (typ), 1700 μV (max over temp) - ensures ≤1.7 mV error in 12-bit ADC reference buffering at 3.3 V full-scale. |
| Input noise voltage | 11 nV/√Hz at 1 kHz - preserves SNR in sensor signal chains where thermal noise dominates below 10 kHz. |
| Common-mode rejection | 71 dB (min), 85 dB (typ) - rejects battery rail fluctuations in HEV battery cell voltage monitoring with <100 μV error at 1 V common-mode shift. |

| 1SHDN | Shutdown control, channel 1 | Active-low TTL-compatible enable; pulls channel 1 supply current to 0.3 μA when <0.7 V applied. |
| VDD+ | Positive supply | Single-supply input (2.7–6 V); powers all four channels; decoupling capacitor (≥100 nF) required at pin. |
| 2OUT | Output, channel 2 | Independent output; identical electrical specs to 1OUT; shares VDD+ and GND with other channels. |
| 2IN– | Inverting input, channel 2 | Electrically isolated from channel 1 inputs; supports separate feedback networks without crosstalk. |
| 2IN+ | Noninverting input, channel 2 | Matched performance to 1IN+; enables dual-sensor differential measurement with common reference. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464QPWRQ1 | Higher input offset voltage (2000 μV max vs. 1700 μV), no A-grade trimming; same pinout and shutdown logic. | Acceptable for non-critical signal paths (e.g., status indication) but not recommended for precision BMS cell monitoring. | Select TLV2464AQPWRQ1 when <1.7 mV absolute offset error is required across –40°C to +125°C. |
| LMV324QDRQ1 | Lower bandwidth (1 MHz), no shutdown function, higher supply current (120 μA/channel), rail-to-rail output only (not input). | Suitable for cost-sensitive, low-speed applications like cabin temperature sensing - not viable for HEV inverter current loops. | Choose TLV2464AQPWRQ1 when 6.4 MHz bandwidth, individual shutdown, and rail-to-rail input are mandatory. |
Compared with TLV2464QPWRQ1 and LMV324QDRQ1, the TLV2464AQPWRQ1 provides tighter offset voltage grading, higher bandwidth, and per-channel shutdown - making it the only option among the three qualified for precision, power-scalable HEV/EV subsystems requiring AEC-Q100 Grade 1 compliance.

FAQ
What is the operating temperature range for the TLV2464AQPWRQ1?
The TLV2464AQPWRQ1 is qualified per AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. This rating is validated across all electrical parameters in the datasheet, including input offset voltage, CMRR, and supply current, ensuring reliability in engine bay and powertrain environments where thermal stress is extreme.
Does the TLV2464AQPWRQ1 support true rail-to-rail input?
Yes, the TLV2464AQPWRQ1 features rail-to-rail input capability: its common-mode input voltage range extends from –0.2 V to VDD + 0.2 V. This allows direct interfacing with sensors or DACs operating at ground or supply rail levels - critical for low-voltage battery monitoring where traditional op-amps would clip near the rails.
How does the shutdown function work on the TLV2464AQPWRQ1?
The TLV2464AQPWRQ1 provides four independent shutdown pins (1SHDN through 4SHDN). Driving any SHDN pin below 0.7 V places its corresponding amplifier into ultra-low-power mode (0.3 μA/channel), disabling output stage and setting output to high-impedance. Pins left unconnected or pulled high (>2 V) maintain normal operation.
What is the maximum capacitive load the TLV2464AQPWRQ1 can drive stably?
The TLV2464AQPWRQ1 remains stable with capacitive loads up to 160 pF when configured as a unity-gain buffer with 10 kΩ load resistance, as verified by 45° phase margin and 7 dB gain margin in the datasheet. For loads exceeding 160 pF, an isolation resistor (e.g., 10–50 Ω) between output and capacitance is recommended to preserve stability.
Is the TLV2464AQPWRQ1 pin-compatible with standard TLV2464 variants?
Yes, the TLV2464AQPWRQ1 uses the same TSSOP-14 footprint and pin assignment as non-automotive TLV2464A variants (e.g., TLV2464AIPWR), including identical 1OUT, 1IN–, 1IN+, GND, NC, 1SHDN, VDD+, 2OUT, 2IN–, 2IN+, 2SHDN, 3IN+, 3IN–, 3OUT, 4IN–, 4IN+, and 4OUT mapping - enabling drop-in replacement in existing designs requiring AEC-Q100 compliance.
