Product details
Overview
TLV2464CPWR from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-power portable and industrial signal conditioning. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage - enabling high-fidelity buffering of ADC inputs in battery-powered sensor front-ends.
For engineers reviewing the TLV2464CPWR datasheet, TLV2464CPWR pinout, TLV2464CPWR application, or TLV2464CPWR equivalent, this device is selected for precision analog signal chains requiring rail-to-rail swing, low quiescent current, wide supply range (2.7–6 V), and operation across −40°C to 125°C in TSSOP-14 packaging.
Technical Context
The TLV2464CPWR integrates four independent amplifiers with complementary-input-stage architecture enabling true rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing. Each channel features internal compensation for unity-gain stability with capacitive loads up to 160 pF.
It supports shutdown functionality via dedicated SHDN pins (pins 1/2 and 13/14), reducing per-channel supply current to 0.3 µA while placing outputs in high-impedance state - critical for power-gated multi-channel systems without signal contention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to ~100 kHz at gain ≥ 64 with minimal phase margin degradation. |
| Slew Rate | 1.6 V/µs - supports 10-bit ADC sampling at 1 MSPS with ≤0.1% distortion for 2-VPP signals. |
| Input Offset Voltage | 100 µV (typ) - contributes ≤0.001% error in 10-V full-scale precision measurement paths. |
| Supply Current / Channel | 500 µA - allows 4-channel operation at <2 mA total, suitable for always-on sensor nodes. |
| Rail-to-Rail I/O | Input: 0 V to VDD; Output: within 100 mV of rails at ±10 mA - maximizes dynamic range in 3.3-V single-supply systems. |
| Output Drive | ±80 mA - drives 50-Ω transmission lines or multiple 10-kΩ ADC inputs without external buffers. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - maintains SNR > 90 dB for audio-band and low-frequency sensor signals. |
Pinout & Package
TSSOP-14 package (4.4 mm × 5.0 mm, 0.65 mm pitch), thermally enhanced for continuous 4-channel operation at ambient temperatures up to 125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 | Channel 1/2 Shutdown Control | Active-high logic input; <0.7 V disables amplifier, >2 V enables; ties to VDD or microcontroller GPIO. |
| 2, 14 | Channel 3/4 Shutdown Control | Independent control for dual-pair shutdown sequencing in multi-stage signal chains. |
| 3, 5, 8, 10 | Inverting Inputs (−) | High-impedance differential inputs (10⁹ Ω); accept signals from sensors, DACs, or filters. |
| 4, 6, 9, 11 | Non-inverting Inputs (+) | Matched to inverting inputs; enable precision instrumentation, reference buffering, and active filtering. |
| 7 | Ground (GND) | Common return for all channels; requires low-impedance PCB plane for noise immunity. |
| 12 | Positive Supply (VDD+) | Single 2.7–6 V or split ±1.35–±3 V supply; decoupling capacitor required at pin. |
| 1, 2, 4, 6, 8, 9, 10, 11, 13, 14 | Outputs (OUT1–OUT4) | Rail-to-rail sourcing/sinking up to ±80 mA; high-Z during shutdown prevents back-driving. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IPWR | Same electrical specs but rated for −40°C to +125°C (I-suffix) vs C-suffix (0°C to +70°C); identical TSSOP-14 package and pinout. | Required for industrial automation or automotive body electronics where extended temperature operation is mandatory. | Select TLV2464IPWR when ambient operating temperature exceeds 70°C or long-term reliability at temperature extremes is required. |
| OPA4340UA | Higher precision: 50 µV max VIO, 5.5 MHz GBW, 1.5 V/µs slew rate; 750 µA/channel supply current; SOIC-14 package. | Better suited for metrology-grade applications demanding lower offset and drift, but consumes 50% more quiescent current. | Choose OPA4340UA only when offset voltage <50 µV and drift <0.2 µV/°C are critical - not for general-purpose low-power use. |
Compared with TLV2464CPWR, TLV2464IPWR offers identical performance with extended temperature qualification, while OPA4340UA trades higher power for improved DC precision - making TLV2464CPWR optimal for cost-sensitive, battery-constrained designs requiring robust rail-to-rail operation across commercial temperature range.

FAQ
What is the maximum operating temperature range for TLV2464CPWR?
The TLV2464CPWR is specified for operation from 0°C to +70°C (C-suffix). Its absolute maximum junction temperature is 150°C, but sustained operation above 70°C ambient requires thermal design verification using the θJA = 173.6°C/W value for the TSSOP-14 package. For designs requiring −40°C to +125°C operation, TI recommends TLV2464IPWR instead.
Does TLV2464CPWR support true rail-to-rail input and output?
Yes, TLV2464CPWR provides true rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 100 mV of rails at ±10 mA). This is confirmed in the datasheet's "Recommended Operating Conditions" and "Electrical Characteristics" tables for both 3-V and 5-V supplies, enabling full dynamic range utilization in single-supply 3.3-V systems.
How does the shutdown feature work on TLV2464CPWR?
TLV2464CPWR has two independent shutdown controls: pins 1/2 disable channels 1/2, and pins 13/14 disable channels 3/4. Driving these pins below 0.7 V places the corresponding amplifier in ultralow-current mode (0.3 µA/channel) and forces its output into high-impedance state. No external pull-up is required - internal bias ensures defined state during power-up.
What is the typical input offset voltage for TLV2464CPWR?
The typical input offset voltage for TLV2464CPWR is 100 µV at 25°C and VDD = 3 V, with a maximum of 2000 µV over the full 0°C to +70°C temperature range. The datasheet also specifies a temperature coefficient of 2 µV/°C, meaning offset drift remains tightly bounded across its commercial operating range.
Can TLV2464CPWR drive capacitive loads without oscillation?
Yes, TLV2464CPWR is internally compensated for unity-gain stability with capacitive loads up to 160 pF, as verified in the "Operating Characteristics" table and Figure 36 (Phase Margin vs Load Capacitance). For loads exceeding 160 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to maintain phase margin >44°.
