Product details
Overview
TLV2464AMDREPG4 from Texas Instruments is a quad rail-to-rail input/output operational amplifier designed for low-voltage portable systems. It delivers 6.4 MHz gain bandwidth, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage - enabling high-fidelity analog signal buffering in battery-powered data acquisition and sensor interface applications.
For engineers reviewing the TLV2464AMDREPG4 datasheet, TLV2464AMDREPG4 pinout, TLV2464AMDREPG4 application, or TLV2464AMDREPG4 equivalent, key selection criteria include extended temperature operation (−55°C to 125°C), shutdown mode (0.3 µA/channel), rail-to-rail output swing, and D-package 14-pin SOIC compatibility with industrial-grade qualification pedigree.
Technical Context
The TLV2464AMDREPG4 implements a CMOS input stage with rail-to-rail common-mode input range extending beyond supply rails, supporting full dynamic range in single-supply 2.7–6 V systems. Its output stage delivers true rail-to-rail swing with ±80 mA sourcing/sinking capability at 5 V, overcoming limitations of legacy rail-to-rail op-amps.
It integrates individual shutdown control per channel (SHDN pins), placing unused amplifiers into ultralow 0.3 µA/channel current state while maintaining high-impedance output. The device meets JEDEC-qualified reliability standards for extended temperature operation, including HAST, temperature cycling, and bond intermetallic life testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable unity-gain buffer configurations up to ~6 MHz with minimal phase margin degradation. |
| Slew Rate | 1.6 V/µs - enables clean 100 kHz full-scale sine wave output at 2 VPP without distortion. |
| Input Offset Voltage | 100 µV - ensures ≤0.002% error in 5 V full-scale precision instrumentation front-ends. |
| Supply Current / Channel | 500 µA - allows four-channel operation at <2 mA total, critical for coin-cell or energy-harvesting systems. |
| Rail-to-Rail Output | Swings within 100 mV of VDD/GND at 10 mA load - maximizes ADC input dynamic range in 3.3 V systems. |
| Shutdown Current / Channel | 0.3 µA - reduces quiescent power by >99.9% when disabled, preserving battery life in duty-cycled sensors. |
| Operating Temperature | −55°C to 125°C - qualified for aerospace, downhole, and automotive under-hood environments. |
Pinout & Package
TLV2464AMDREPG4 is housed in a 14-pin SOIC (D package) with exposed pad for thermal enhancement. Pin numbering follows standard top-view orientation with pin 1 marked by notch or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of amplifier channel 1 - drives external load directly; rail-to-rail swing capability enables direct ADC interface. |
| 2 | 1IN− | Inverting input of channel 1 - high-impedance CMOS node; supports precision differential sensing with matched feedback networks. |
| 3 | 1IN+ | Non-inverting input of channel 1 - extends beyond supply rails (−0.2 V to VDD+0.2 V), enabling ground-referenced sensor inputs on single supply. |
| 4 | GND | Analog ground reference - must be low-impedance star point; separates from digital ground to minimize noise coupling. |
| 5 | NC | No internal connection - left unconnected; no routing or thermal relief required. |
| 6 | 1SHDN | Channel 1 shutdown control - logic-low (<0.7 V) disables amplifier and reduces current to 0.3 µA; open or high enables operation. |
| 7 | NC | No internal connection - unused; electrically isolated from die. |
| 8 | VDD+ | Positive supply rail - accepts 2.7–6 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin. |
| 9 | 2OUT | Output of channel 2 - independent output path; supports dual-sensor conditioning or active filtering stages. |
| 10 | 2IN− | Inverting input of channel 2 - electrically identical to pin 2; enables matched multi-channel designs. |
| 11 | 2IN+ | Non-inverting input of channel 2 - same rail-to-rail input range as pin 3; supports synchronous multi-channel acquisition. |
| 12 | NC | No internal connection - no internal bond wire; PCB pad may be grounded for thermal improvement if needed. |
| 13 | 2SHDN | Channel 2 shutdown control - independent logic control per channel; enables selective power gating in multi-stage signal chains. |
| 14 | NC | No internal connection - floating; no electrical or thermal function. |

FAQ
What is the maximum operating temperature range for TLV2464AMDREPG4?
The TLV2464AMDREPG4 is rated for continuous operation from −55°C to 125°C. This extended temperature range is verified through JEDEC-qualified reliability testing including biased 85/85, temperature cycling, and HAST - confirming suitability for aerospace, downhole, and automotive under-hood applications where standard commercial op-amps fail.
Does TLV2464AMDREPG4 support true rail-to-rail input and output?
Yes, TLV2464AMDREPG4 supports true rail-to-rail input (common-mode range extends to −0.2 V below GND and VDD+0.2 V) and rail-to-rail output (swings within 100 mV of both rails at 10 mA load). This enables full utilization of ADC input range in single-supply 3.3 V systems without external level-shifting components.
How does the shutdown feature work on TLV2464AMDREPG4?
TLV2464AMDREPG4 provides dedicated SHDN pins (pins 6 and 13) for channels 1 and 2 respectively. Driving either pin below 0.7 V places its associated amplifier into ultralow-power shutdown mode, reducing supply current to 0.3 µA/channel while forcing the output into high-impedance state - enabling selective power gating in multi-stage analog signal paths.
What is the typical input offset voltage specification for TLV2464AMDREPG4?
The typical input offset voltage for TLV2464AMDREPG4 is 100 µV at 25°C and VDD = 5 V, with a maximum of 1700 µV across the full −55°C to 125°C temperature range. This low offset enables high-accuracy DC-coupled applications such as precision sensor amplification and medical biosignal conditioning without external trimming.
Is TLV2464AMDREPG4 compatible with standard SOIC-14 footprints?
Yes, TLV2464AMDREPG4 uses the industry-standard 14-pin SOIC (D package) footprint with 1.27 mm pitch and 8.65 mm × 3.91 mm body dimensions. It is mechanically and solder-reflow compatible with standard SOIC-14 land patterns, allowing drop-in replacement in existing designs using TI's TLV2464x family or equivalent quad op-amps in the same package.
