Product details
Overview
TLV2465CN from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-voltage portable systems. 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 signal buffering in ADC front-ends and sensor interfaces.
For engineers reviewing the TLV2465CN datasheet, TLV2465CN pinout, TLV2465CN application, or TLV2465CN equivalent, this device is selected for precision analog signal conditioning where rail-to-rail swing, micropower operation, and shutdown capability (0.3 µA/channel) are critical in battery-powered instrumentation and industrial sensing nodes.
Technical Context
The TLV2465CN implements a CMOS input stage with rail-to-rail input common-mode range extending beyond supply rails (0 V to VDD), and rail-to-rail output swing delivering full dynamic range at 2.7–6 V single-supply operation. Its architecture supports stable unity-gain configuration with 45° phase margin into 160 pF capacitive loads.
Each of its four amplifiers features independent shutdown control (pin 1/2SHDN and 3/4SHDN), placing the channel in high-impedance output state while reducing supply current to 0.3 µA per channel. DC performance includes 11 nV/√Hz input noise voltage and 85 dB CMRR at 25°C, supporting precision DC-coupled applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to ~1 MHz at unity gain with adequate phase margin. |
| Slew Rate | 1.6 V/µs - supports 10-bit ADC sampling at ≥100 kSPS with <0.1% distortion for 2 VPP signals. |
| Supply Current / Channel | 500 µA - allows four-channel operation under 2 mA total, suitable for always-on sensor signal chains. |
| Input Offset Voltage | 100 µV - ensures ≤0.004% gain error in 2.5 V full-scale 16-bit measurement systems. |
| Rail-to-Rail I/O | Input range: 0 V to VDD; Output swing: within 100 mV of rails - maximizes SNR in low-voltage ADC drivers. |
| Shutdown Current | 0.3 µA/channel - reduces quiescent power by >99.9% during idle periods in duty-cycled systems. |
| Output Drive | ±80 mA - drives 10 kΩ loads with <0.1 V headroom, sufficient for driving SAR ADC reference buffers and active filters. |
Pinout & Package
TLV2465CN is housed in a 16-pin plastic DIP (N) package with through-hole mounting and 0.3-inch body width. Pin 1 is located at the left end of the top row, identified by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 12 | 1/2SHDN, 3/4SHDN | Active-high dual shutdown control: pins 1 and 12 independently disable channels 1&2 and 3&4 respectively. |
| 2, 6, 9, 13 | 1IN−, 2IN−, 3IN−, 4IN− | Inverting inputs - high-impedance CMOS nodes (IIB = 1.3 nA typ @ 5 V) for precision feedback networks. |
| 3, 5, 10, 14 | 1IN+, 2IN+, 3IN+, 4IN+ | Non-inverting inputs - support rail-to-rail common-mode range (0 V to VDD) for direct sensor interfacing. |
| 4, 11 | GND, VDD+ | Power terminals - GND (pin 4) and VDD+ (pin 11) define the single-supply operating domain (2.7–6 V). |
| 1, 7, 8, 15 | 1OUT, 2OUT, 3OUT, 4OUT | Amplifier outputs - rail-to-rail capable with ±80 mA sourcing/sinking, usable as buffer or active filter stages. |
| 16 | NC | No internal connection - unused pad; no electrical function or thermal tie required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2465IDR | Same core specs but in 14-pin TSSOP (PW) package; rated for −40°C to 125°C (I-suffix); no NC pin. | Better suited for space-constrained PCBs requiring surface-mount assembly and extended temperature operation. | Select TLV2465IDR when board area is limited and automotive/industrial temperature range is mandatory. |
| OPA4340UA | Lower input offset (125 µV max), higher GBW (5.5 MHz), lower noise (8 nV/√Hz), but no shutdown and 1.2 mA/channel supply current. | Preferred for ultra-low-noise, high-precision DC applications where power budget permits and shutdown is unnecessary. | Choose OPA4340UA only if noise and offset dominate over power and feature set - not a drop-in replacement. |
Compared with TLV2465CN, TLV2465IDR offers identical functionality in a smaller footprint and wider temperature grade, while OPA4340UA trades shutdown and micropower for superior DC precision and noise - making TLV2465CN optimal for cost-sensitive, battery-aware, multi-channel signal chains requiring flexible power management.

FAQ
What is the operating supply voltage range for the TLV2465CN?
The TLV2465CN operates from a single supply of 2.7 V to 6 V, or split supplies of ±1.35 V to ±3 V. This wide range supports both low-voltage portable designs (e.g., 3.3 V microcontroller systems) and legacy 5 V industrial platforms without external level-shifting circuitry.
Does the TLV2465CN support true rail-to-rail input and output operation?
Yes, the TLV2465CN provides rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 100 mV of each rail under load). This enables maximum dynamic range in single-supply configurations, such as driving ADCs directly from 3.3 V or 5 V rails.
How does the shutdown feature work on the TLV2465CN?
The TLV2465CN has two independent shutdown pins: pin 1 (1/2SHDN) disables channels 1 and 2, and pin 12 (3/4SHDN) disables channels 3 and 4. Driving either pin below 0.7 V places the associated pair in ultralow-current mode (0.3 µA/channel) with high-impedance outputs.
What is the typical input offset voltage and temperature drift of the TLV2465CN?
The TLV2465CN has a typical input offset voltage of 100 µV at 25°C and a maximum of 1500 µV over the full −40°C to 125°C range. Its temperature coefficient is 2 µV/°C, ensuring predictable, low-drift performance in thermally varying environments like automotive or industrial enclosures.
Can the TLV2465CN drive capacitive loads commonly found at ADC inputs?
Yes - the TLV2465CN maintains stability with up to 160 pF capacitive loads at unity gain (45° phase margin), making it suitable for direct connection to SAR ADC inputs (typically 10–30 pF) plus PCB trace capacitance without external isolation resistors.
