Product details
Overview
TLV2465IN from Texas Instruments is a quad rail-to-rail input/output operational amplifier with 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive capability, 500 µA/channel supply current, and 100 µV input offset voltage. It operates from 2.7 V to 6 V single supply and supports industrial and automotive temperature ranges (−40°C to 125°C), making it suitable for precision analog front-ends in data acquisition systems.
For engineers reviewing the TLV2465IN datasheet, TLV2465IN pinout, TLV2465IN application, or TLV2465IN equivalent, this device delivers rail-to-rail dynamic range, micropower shutdown (0.3 µA/channel), low-noise performance (11 nV/√Hz), and high-output-drive capability-key selection criteria for ADC buffering, sensor signal conditioning, and battery-powered instrumentation.
Technical Context
The TLV2465IN implements a CMOS input stage enabling rail-to-rail common-mode input voltage range (0 V to VDD) and rail-to-rail output swing, critical for maximizing dynamic range in low-voltage systems. Its architecture supports stable unity-gain operation with 160 pF capacitive load and provides 45° phase margin at 5 V supply.
Each of its four amplifiers features independent shutdown control (SHDN pins), placing the output in high-impedance state and reducing supply current to 0.3 µA per channel. The device maintains 85 dB CMRR and 85 dB PSRR across 2.7–6 V supply, ensuring robust performance in noisy industrial environments.
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. |
| Slew Rate | 1.6 V/µs - supports 10-bit settling within 1 µs for 2 Vpp signals at unity gain. |
| Output Drive | ±80 mA - drives heavy loads (e.g., 62 Ω at 5 V) without external buffers. |
| Supply Current | 500 µA/channel - enables multi-amplifier designs in power-constrained applications. |
| Input Offset Voltage | 100 µV (typ) - ensures <0.002% gain error in 5 V full-scale precision gain stages. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - preserves SNR in sensor interfaces with bandwidths <100 kHz. |
| Rail-to-Rail I/O | Input: 0 V to VDD; Output: within 100 mV of rails - maximizes usable signal swing in 3.3 V systems. |
Pinout & Package
TLV2465IN is housed in a 16-pin plastic DIP (N) package with through-hole mounting and 0.3-inch body width. Pin 1 is identified by a beveled edge or molded dot.

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 |
|---|---|---|---|
| TLV2464IN | No shutdown function; identical pinout, GBW (6.4 MHz), noise (11 nV/√Hz), and supply current (500 µA/ch). | Used where channel enable/disable is unnecessary; lower BOM cost due to reduced control logic. | Select TLV2464IN when power sequencing or dynamic channel disable is not required. |
| OPA4340UA | Higher precision: 25 µV VIO (max), 5.5 MHz GBW, 1.25 V/µs slew rate; 750 µA/ch supply current; no shutdown. | Preferred in high-accuracy medical or test equipment where offset drift dominates error budget. | Choose OPA4340UA when sub-50 µV offset and <0.1 µV/°C drift outweigh power and feature trade-offs. |
Compared with TLV2465IN, TLV2464IN removes shutdown capability but retains identical AC performance and power consumption, while OPA4340UA trades higher supply current and no shutdown for significantly improved DC precision-making TLV2465IN optimal for cost-sensitive, power-aware industrial systems requiring flexible channel control.

FAQ
What is the operating temperature range for TLV2465IN?
The TLV2465IN is rated for operation from −40°C to +125°C, meeting industrial and automotive qualification standards. This range is confirmed in the "Recommended Operating Conditions" table of the SLOS220J datasheet, and applies to the N-package variant with I-suffix marking. It supports deployment in under-hood automotive ECUs and factory-floor PLC modules without thermal derating.
Does TLV2465IN support true rail-to-rail input and output?
Yes, TLV2465IN supports rail-to-rail input (common-mode range = 0 V to VDD) and rail-to-rail output (swing within 100 mV of both rails at ±80 mA load). This is explicitly specified in the device description and verified in electrical characteristics tables for VOH/VOL at 2.5 mA and 10 mA loads across 3 V and 5 V supplies.
How does the shutdown function work on TLV2465IN?
TLV2465IN has two independent shutdown pins: Pin 12 (1/2SHDN) controls Amplifiers A and B; Pin 16 (3/4SHDN) controls Amplifiers C and D. Driving either pin below 0.7 V places its associated pair into ultralow-current shutdown (0.3 µA/channel), with output in high-impedance state. This is documented in the "Electrical Characteristics" table under IDD(SHDN).
What is the maximum capacitive load TLV2465IN can drive stably?
TLV2465IN maintains stability with up to 160 pF capacitive load at unity gain, as confirmed by phase margin (45°) and gain margin (7 dB) measurements in the "Operating Characteristics" section at VDD = 5 V. For loads >100 pF, TI recommends using a small series resistor (e.g., 10–50 Ω) between amplifier output and capacitor to preserve phase margin.
Is TLV2465IN pin-compatible with other TLV246x variants in the same package?
Yes, TLV2465IN is pin-compatible with TLV2464IN (quad no-shutdown) and TLV2462IN (dual with shutdown) in the 16-pin N-package, sharing identical pin assignments for IN+, IN−, OUT, GND, VDD+, and SHDN terminals. This allows direct substitution in existing layouts when adding or removing shutdown functionality.
