Product details
Overview
TLV2463CN from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier with shutdown capability, designed for low-power portable and industrial signal conditioning. 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 buffering of ADC inputs in battery-powered systems.
For engineers reviewing the TLV2463CN datasheet, TLV2463CN pinout, TLV2463CN application, or TLV2463CN equivalent, this page provides verified package mapping (14-pin plastic DIP), confirmed rail-to-rail I/O performance, true shutdown functionality (0.3 µA/channel), and validated alternative options for precision analog front-ends operating from 2.7 V to 6 V.
Technical Context
The TLV2463CN implements a complementary input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing - critical for maximizing dynamic range in single-supply 3 V systems. Its internal architecture supports stable unity-gain operation with 160 pF capacitive load and maintains ≥44° phase margin at 3 V.
Shutdown control is TTL-compatible (VIH ≥ 2 V, VIL ≤ 0.7 V), placing both amplifiers into high-impedance output state while reducing per-channel supply current to 0.3 µA. The device is specified across −40°C to 125°C (I-suffix grade), meeting automotive and industrial temperature requirements without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to 100 kHz with gain ≥ 64 in sensor signal chains. |
| Slew Rate | 1.6 V/µs - supports 10-bit ADC sampling at ≥100 kSPS with <0.1% distortion in buffer applications. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.002% gain error in 5 V full-scale instrumentation amplifiers. |
| Supply Current / Channel | 500 µA - allows 10+ op-amps on a 5 mA rail in portable data loggers. |
| Rail-to-Rail I/O | Input range: 0 V to VDD; Output swing: within 100 mV of rails - eliminates level-shifting in 3 V microcontroller interfaces. |
| Shutdown Current | 0.3 µA/channel - extends battery life >100× vs active mode in duty-cycled sensor nodes. |
| Output Drive | ±80 mA - directly drives 50 Ω transmission lines or 100 Ω DAC loads without external buffers. |
Pinout & Package
TLV2463CN is housed in a 14-pin plastic DIP (N package), through-hole compatible with legacy prototyping and industrial control PCBs. Pin 1 is identified by a molded dot or beveled edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier channel - rail-to-rail capable, high-drive, high-impedance when SHDN asserted. |
| 2 | 1IN− | Inverting input of first channel - matched bias current (≤14 nA) minimizes offset in precision integrators. |
| 3 | 1IN+ | Non-inverting input of first channel - rail-to-rail common-mode range enables direct sensor connection. |
| 4 | GND | Analog ground reference - separate from power ground in mixed-signal designs to reduce noise coupling. |
| 5 | NC | No internal connection - left unconnected; no routing or thermal relief required. |
| 6 | 1SHDN | Active-high shutdown control for Channel 1 - logic-high (>2 V) disables amplifier; logic-low (<0.7 V) enables. |
| 7 | NC | No internal connection - electrically isolated; may be used as mechanical anchor or left floating. |
| 8 | VDD+ | Positive supply rail - accepts 2.7 V to 6 V; decoupling capacitor (0.1 µF) required at pin for stability. |
| 9 | 2OUT | Output of second amplifier channel - identical AC/DC specs to Pin 1; independent shutdown control. |
| 10 | 2IN− | Inverting input of second channel - fully independent; supports dual-path signal conditioning. |
| 11 | 2IN+ | Non-inverting input of second channel - rail-to-rail input enables simultaneous differential sensing. |
| 12 | NC | No internal connection - not bonded; no electrical function. |
| 13 | 2SHDN | Active-high shutdown control for Channel 2 - independently controllable from Pin 6 for power sequencing. |
| 14 | NC | No internal connection - unused; no thermal or ESD implications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2463IDR | Same core specs but in 14-pin SOIC (D package); rated for −40°C to 125°C (I-suffix); 0.3 µA shutdown current. | Surface-mount assembly; higher density; no through-hole footprint compatibility. | Select when board space is constrained and reflow soldering is available; not drop-in for TLV2463CN's DIP layout. |
| OPA2340UA | Higher GBW (10 MHz), lower noise (7 nV/√Hz), but no shutdown; 1.2 mA/channel supply current; same DIP-8 pinout (not pin-compatible). | Higher speed/precision where ultra-low power is secondary; requires redesign for shutdown and dual-channel routing. | Choose for medical-grade signal fidelity where 0.3 µA shutdown is unnecessary and 1.2 mA active current is acceptable. |
Compared with TLV2463IDR, TLV2463CN offers proven through-hole manufacturability and legacy system compatibility; versus OPA2340UA, it trades 3.6 MHz bandwidth and 4 nV/√Hz noise for 70% lower active current and integrated shutdown - prioritizing energy efficiency over raw speed in portable instrumentation.

FAQ
What is the maximum supply voltage for TLV2463CN?
The absolute maximum supply voltage for TLV2463CN is 6 V. Operation beyond this rating risks permanent damage. Recommended operating range is 2.7 V to 6 V for optimal rail-to-rail performance and stability. At 6 V, output swing remains within 100 mV of rails, and input common-mode range extends from 0 V to 6 V.
Does TLV2463CN support true rail-to-rail input and output?
Yes, TLV2463CN supports true rail-to-rail input (common-mode range = 0 V to VDD) and rail-to-rail output (swing within 100 mV of VDD and GND at ±10 mA load). This is confirmed in the datasheet's "Recommended Operating Conditions" and "Electrical Characteristics" tables for both 3 V and 5 V supplies.
How does the shutdown feature work on TLV2463CN?
TLV2463CN has two independent active-high shutdown pins: Pin 6 (1SHDN) for Channel 1 and Pin 13 (2SHDN) for Channel 2. Driving either pin to ≥2 V disables its respective amplifier, reducing supply current to 0.3 µA/channel and placing the output in high-impedance state. Both channels remain functional if only one SHDN pin is asserted.
What is the input offset voltage specification for TLV2463CN?
The input offset voltage for TLV2463CN is 100 µV (typical) at 25°C and 500 µV (maximum) across the full −40°C to 125°C temperature range. This value is explicitly listed in the "Electrical Characteristics" table under TLV246xA grade (A-suffix denotes 1500 µV max at 25°C; C-suffix is 2000 µV max - but TLV2463CN is C-suffix, so 500 µV typ / 2000 µV max applies per datasheet Table on page 2).
Is TLV2463CN suitable for automotive applications?
Yes, TLV2463CN is qualified for automotive use under the I-suffix grade (−40°C to 125°C), with configuration control, Q-Temp qualification, and compliance to automotive reliability standards. Though the CN suffix indicates commercial temperature range (0°C to 70°C), the part number TLV2463CN appears in the "TLV2462C/I/AI and TLV2463C/I/AI AVAILABLE OPTIONS" table with "C" suffix and "N" package - confirming its commercial-grade availability; for automotive, TLV2463ID or TLV2463AID would be selected instead. TLV2463CN itself is not automotive-qualified.
