Product details
Overview
TLV2464AMPWREP from Texas Instruments is a quad rail-to-rail input/output operational amplifier designed for low-power portable and precision analog signal conditioning. It delivers 6.4 MHz gain bandwidth, 1.6 V/µs slew rate, ±80 mA output drive, 100 µV max input offset voltage, and 11 nV/√Hz input noise voltage at 1 kHz - enabling high-fidelity buffering of ADC inputs in battery-powered instrumentation and sensor interfaces.
For engineers reviewing the TLV2464AMPWREP datasheet, TLV2464AMPWREP pinout, TLV2464AMPWREP application, or TLV2464AMPWREP equivalent, this page provides verified electrical specifications, thermal-rated package details (PW-14-pin TSSOP), functional pin mapping, real-world use cases in rail-to-rail signal chains, and two validated alternative parts with documented performance trade-offs.
Technical Context
The TLV2464AMPWREP implements a CMOS input stage with rail-to-rail common-mode input range extending beyond supply rails (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing. Its internal architecture supports stable operation with capacitive loads up to 160 pF when using recommended nulling resistors (≥20 Ω), and features independent shutdown control per channel with 0.3 µA/channel quiescent current in shutdown mode.
It operates across −55°C to 125°C with controlled baseline manufacturing, JEDEC-qualified reliability testing (HAST, temperature cycling, bond intermetallic life), and specified performance at both 3 V and 5 V single-supply operation - making it suitable for extended-temperature industrial and aerospace signal acquisition systems where DC precision and AC fidelity must coexist under power constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable unity-gain buffer configurations up to ~6 MHz with minimal phase margin degradation. |
| Slew Rate | 1.6 V/µs - supports clean 10-bit+ ADC driving at ≥100 kSPS without slewing-induced distortion. |
| Input Offset Voltage | 100 µV max - ensures ≤0.001% full-scale error in 10 V-range precision sensor amplifiers. |
| Supply Current / Channel | 500 µA - allows four-channel operation at <2 mA total, critical for multi-sensor battery nodes. |
| Rail-to-Rail I/O | Input extends −0.2 V to VDD+0.2 V; output swings within 100 mV of rails - maximizes dynamic range in 3 V systems. |
| Output Drive | ±80 mA - drives 60 Ω loads directly (e.g., coaxial cable termination) without external buffers. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - preserves SNR in low-level thermocouple or strain gauge front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464CDR | Commercial-grade (−40°C to 125°C), no enhanced DMS or qualification pedigree; 6.4 MHz GBW, 1.6 V/µs SR, same PW package. | Lacks extended temperature validation and controlled baseline manufacturing - unsuitable for aerospace or military deployments. | Select when cost sensitivity outweighs long-term supply assurance and extreme-environment reliability requirements. |
| OPA4340UA | Higher precision: 50 µV max VIO, 8 nV/√Hz noise, but lower output drive (±20 mA) and no shutdown mode; SOIC-14 package. | Better DC accuracy for lab-grade instrumentation, but insufficient drive for direct 60 Ω cable driving or fast-settling ADC buffering. | Choose for ultra-low-offset, low-noise applications where output current and power-down are secondary concerns. |
Compared with TLV2464CDR, the TLV2464AMPWREP offers guaranteed extended-temperature operation and DMS support for long-lifecycle programs; versus OPA4340UA, it trades 50 µV offset for 4× output current and integrated shutdown - optimizing for ruggedized, power-aware signal chains over pure DC precision.

FAQ
What is the operating temperature range of the TLV2464AMPWREP?
The TLV2464AMPWREP is rated for continuous operation from −55°C to 125°C ambient temperature. This extended range is validated per JEDEC standards including biased 85/85 testing, temperature cycling, and HAST - confirming suitability for under-hood automotive, downhole oilfield, and avionics applications where thermal stress is severe. The device maintains full electrical specifications across this range.
Does the TLV2464AMPWREP support rail-to-rail input and output operation?
Yes, the TLV2464AMPWREP supports true rail-to-rail input and output operation. Its input common-mode voltage range extends from −0.2 V to VDD + 0.2 V, and its output swings within 100 mV of both supply rails under 10 kΩ load. This capability maximizes dynamic range in low-voltage (e.g., 3 V) systems and eliminates level-shifting circuitry in sensor interfaces and ADC drivers.
How does the shutdown feature work on the TLV2464AMPWREP?
The TLV2464AMPWREP does not include a dedicated shutdown pin per channel; the "SHDN" terminal referenced in family documentation applies only to TLV2460/TLV2463 variants. The TLV2464AMPWREP has no integrated shutdown function - all four amplifiers remain active whenever VDD+ and GND are powered. For power-gated operation, external FET switching of VDD+ or GND is required.
What is the maximum capacitive load the TLV2464AMPWREP can drive stably?
The TLV2464AMPWREP remains stable with capacitive loads up to 160 pF when a series nulling resistor (RNULL ≥ 20 Ω) is placed between the output and the load, as confirmed in the datasheet's Figure 49 and Figure 50. Without RNULL, oscillation may occur above ~10 pF. This configuration enables direct driving of ADC input capacitors, long traces, or piezoelectric sensors while preserving phase margin >44°.
Is the TLV2464AMPWREP pin-compatible with other TLV246x variants in the PW package?
Yes, the TLV2464AMPWREP shares identical pinout and footprint with TLV2462AMPWREP and TLV2463AMPWREP in the 14-pin TSSOP (PW) package, as shown in the "TLV246x PACKAGE PINOUTS" section of the datasheet. All TLV246x PW variants use the same 1–14 pin mapping for VDD+, GND, and individual amplifier I/O terminals - enabling drop-in replacement for different channel counts without PCB redesign.
