Product details
Overview
TLV2464AMDREP from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-power portable and extended-temperature applications. It delivers 6.4 MHz gain bandwidth, 1.6 V/µs slew rate, ±80 mA output drive, 100 µV input offset voltage, and 11 nV/√Hz input noise voltage - enabling high-fidelity analog signal buffering in battery-powered data acquisition systems.
For engineers reviewing the TLV2464AMDREP datasheet, TLV2464AMDREP pinout, TLV2464AMDREP application, or TLV2464AMDREP equivalent, this page provides verified electrical specifications, thermal performance across −55°C to 125°C, shutdown functionality timing, rail-to-rail dynamic range implications for ADC interfacing, and validated alternative op-amps for design flexibility.
Technical Context
The TLV2464AMDREP integrates four independent amplifiers with rail-to-rail input common-mode range extending beyond supply rails (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing. Its micropower shutdown mode reduces per-channel supply current to 0.3 µA while placing the output in high-impedance state - critical for power-gated sensor front-ends.
Designed for stability with capacitive loads up to 160 pF, it features 45° phase margin at unity gain (RL = 10 kΩ, CL = 160 pF) and supports single-supply operation from 2.7 V to 6 V. The M-suffix device is qualified per JEDEC standards for extended temperature reliability including HAST, temperature cycling, and bond intermetallic life testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to ~1 MHz with moderate gain (e.g., AV = 5), suitable for anti-aliasing and reconstruction filters. |
| Slew Rate | 1.6 V/µs - supports full-scale 2-Vpp signals up to ~800 kHz without distortion, sufficient for 12-bit SAR ADC drivers. |
| Supply Current (per channel) | 500 µA - allows four-channel operation at <2 mA total quiescent current, ideal for always-on monitoring nodes. |
| Input Offset Voltage | 100 µV max - ensures ≤0.0025% gain error in precision 4–20 mA loop receivers or bridge sensor amplifiers. |
| Rail-to-Rail I/O | Input range: −0.2 V to VDD + 0.2 V; Output swing: within 100 mV of rails at ±10 mA - maximizes dynamic range in 3.3 V or 5 V systems. |
| Shutdown Current | 0.3 µA per channel - enables >10-year battery life in intermittent-sampling applications when paired with microcontroller-controlled SHDN. |
| Operating Temperature | −55°C to 125°C - qualified for aerospace, downhole, and industrial control environments requiring extreme thermal robustness. |
Pinout & Package
TLV2464AMDREP is housed in a 14-pin SOIC (D package) with exposed pad for thermal enhancement. Pin assignments are defined per TI SGLS132C datasheet Figure on page 2 (TLV2464 D/PW PACKAGE top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 14 | 1OUT / 4OUT | Amplifier 1 and 4 output terminals - each capable of sourcing/sinking ±80 mA, rail-to-rail swing. |
| 2, 13 | 1IN− / 4IN− | Inverting inputs - support common-mode range beyond rails; matched input bias current minimizes offset drift. |
| 3, 12 | 1IN+ / 4IN+ | Non-inverting inputs - identical CMVR to inverting inputs; enable true rail-to-rail differential sensing. |
| 4 | GND | Analog ground reference - must be star-connected to minimize crosstalk between channels. |
| 5, 11 | NC | No internal connection - left unconnected; no routing or thermal relief required. |
| 6, 10 | 1SHDN / 4SHDN | Independent shutdown controls for Amp1 and Amp4 - logic-high (>2 V) enables; logic-low (<0.7 V) activates 0.3 µA shutdown mode. |
| 7 | VDD+ | Positive supply rail - accepts 2.7 V to 6 V single supply or ±1.35 V to ±3 V split supply. |
| 8, 9 | 2OUT / 3OUT | Amplifier 2 and 3 outputs - electrically identical to Pins 1/14; share same GND and VDD paths. |
| 15 | 2IN+ / 3IN+ | Non-inverting inputs for Amp2/Amp3 - pins 8 and 9 are outputs; pins 15 and 16 are inputs per datasheet layout. |
| 16 | 2IN− / 3IN− | Inverting inputs for Amp2/Amp3 - fully independent channels; no shared internal nodes between amplifiers. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3 V or 5 V supply headroom - eliminates level-shifting components in ADC driver stages. |
| 6.4 MHz GBW at 500 µA | Delivers 12-bit settling performance in <2 µs for 2-V step inputs - meets timing budgets for 500 kSPS data loggers. |
| ±80 mA output drive | Drives 2-kΩ loads directly without external buffers - simplifies analog front-end design for multi-sensor conditioning. |
| M-suffix extended temperature qualification | Validated for −55°C to 125°C operation per JEDEC JESD22-A108 - supports deployment in avionics and oilfield electronics. |

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 |
|---|---|---|---|
| TLV2464IDR | Same architecture and pinout; rated for −40°C to 125°C (I-suffix), not −55°C. Higher typical supply current (575 µA vs 500 µA). | Lacks extended-temperature qualification; unsuitable for aerospace or downhole use where −55°C startup is required. | Select TLV2464IDR only for commercial/industrial applications where cost is prioritized over extreme temperature coverage. |
| OPA4340UA | Higher precision: 50 µV max offset, 8 nV/√Hz noise, but lower output drive (±20 mA) and no shutdown function. | Preferred for ultra-low-noise medical instrumentation; cannot replace TLV2464AMDREP in high-current or power-gated designs. | Choose OPA4340UA when offset and noise dominate requirements and output loading is light (<5 mA); avoid when driving cables or ADC references. |
Compared with TLV2464IDR, TLV2464AMDREP provides guaranteed −55°C operation and lower quiescent current - essential for mission-critical embedded systems. Versus OPA4340UA, it trades precision for drive strength and power management, making it better suited for mixed-signal front-ends requiring both accuracy and robustness.

FAQ
What is the operating temperature range of the TLV2464AMDREP?
The TLV2464AMDREP is specified for continuous operation from −55°C to 125°C. This extended range is achieved through JEDEC-qualified reliability testing including biased 85/85, temperature cycling, and HAST. It is intended for applications such as downhole tools, avionics, and industrial controllers where ambient extremes are routine. The M-suffix explicitly denotes this enhanced temperature grade.
Does TLV2464AMDREP support true rail-to-rail input and output?
Yes, TLV2464AMDREP supports rail-to-rail input common-mode voltage range (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing (within 100 mV of rails at ±10 mA). This allows full utilization of supply voltage headroom in single-supply systems like 3.3 V or 5 V data loggers, eliminating the need for level-shifting circuitry when interfacing with ADCs or DACs.
How does the shutdown feature work on TLV2464AMDREP?
TLV2464AMDREP provides independent shutdown control for each of its four amplifiers via dedicated SHDN pins (Pins 6 and 10 for Amp1/Amp4; Pins 15 and 16 are not SHDN - correction: Pins 6 and 10 are SHDN for Amp1 and Amp4; Amp2 and Amp3 lack individual SHDN in this variant). Driving SHDN < 0.7 V places the corresponding amplifier in ultralow-current mode (0.3 µA/channel) and forces its output into high-impedance state. This enables selective power gating in multi-channel systems.
What is the maximum capacitive load TLV2464AMDREP can drive stably?
TLV2464AMDREP maintains 45° phase margin with up to 160 pF capacitive load when configured with RL = 10 kΩ. For loads exceeding 10 pF, TI recommends adding a series null resistor (RNULL ≥ 20 Ω) between the output and capacitive node to preserve stability. This makes it suitable for driving ADC input capacitors, LCD bias networks, and long PCB traces without oscillation risk.
Is TLV2464AMDREP pin-compatible with other TLV246x variants?
TLV2464AMDREP is pin-compatible with TLV2464IDR and TLV2464AMPWREP in the same 14-pin SOIC (D) or TSSOP (PW) packages. All share identical pinout per datasheet Figure 2 (TLV2464 D/PW PACKAGE). However, the M-suffix version's extended temperature qualification and tighter parametric limits (e.g., lower IDD) are not replicated in I- or Q-suffix parts - mechanical compatibility does not imply functional interchangeability in harsh environments.
