Product details
Overview
TLV2463IN 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 TLV2463IN datasheet, TLV2463IN pinout, TLV2463IN application, or TLV2463IN equivalent, this device is selected for precision analog front-ends requiring rail-to-rail swing, micropower shutdown (0.3 µA/channel), and operation across −40°C to 125°C in plastic DIP (N) packaging.
Technical Context
The TLV2463IN integrates two independent amplifiers sharing a common shutdown control terminal, supporting independent channel enable/disable sequencing. Its rail-to-rail input stage uses complementary differential pairs extending beyond supply rails, while the output stage employs Class AB push-pull architecture delivering ±80 mA into loads while maintaining linearity up to 1 V from each rail.
Shutdown mode reduces total supply current to 0.3 µA per channel and places the output in high-impedance state, preserving signal integrity in multiplexed or power-gated systems. The amplifier is internally compensated for unity-gain stability with 160 pF capacitive load and exhibits 45° phase margin at 5 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable closed-loop gain ≥10 up to ~600 kHz with minimal phase error. |
| Slew Rate | 1.6 V/µs - enables clean 100-kHz, 1-VPP sine wave reproduction without distortion. |
| Supply Current / Channel | 500 µA - allows continuous operation in 10-µA budget systems when paired with duty-cycled shutdown. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.002% gain error in 5-V full-scale precision sensor interfaces. |
| Output Drive | ±80 mA - drives 60 Ω loads directly (e.g., coaxial cable termination) without external buffers. |
| Rail-to-Rail I/O | Input common-mode range: 0 to VDD; output swing: within 100 mV of rails - maximizes dynamic range in 3.3-V ADC reference designs. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% vs active mode, critical for IoT endpoint sleep states. |
Pinout & Package
TLV2463IN is housed in a 14-pin plastic DIP (N) package with 0.3-inch body width and through-hole mounting. Pin 1 is identified by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output channel A - drives external load or ADC input with rail-to-rail swing. |
| 2 | IN− A | Inverting input for channel A - accepts feedback network or signal source with rail-to-rail common-mode range. |
| 3 | IN+ A | Non-inverting input for channel A - connects to sensor, reference, or filtered signal path. |
| 4 | GND | Analog ground reference - must be low-impedance star point shared with ADC and reference ICs. |
| 5 | NC | No internal connection - left unconnected; no routing or thermal relief required. |
| 6 | SHDN | Active-high shutdown control - logic high (>2 V) enables both channels; low (<0.7 V) disables them. |

| 10 | IN− B | Inverting input for channel B - supports independent gain configuration from channel A. |
| 11 | IN+ B | Non-inverting input for channel B - enables dual-sensor readout or matched filter paths. |
| 12 | NC | No internal connection - no internal bond wire; leave floating. |
| 13 | NC | No internal connection - mechanical filler; no electrical function. |
| 14 | NC | No internal connection - unused; no PCB trace needed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2463IDR | Same core specs but in MSOP-10 (DGK) package; 0.55 mA/ch supply current; rated for −40°C to 125°C. | Surface-mount variant for space-constrained PCBs; lacks DIP's mechanical robustness and hand-solderability. | Select TLV2463IDR for automated assembly in compact consumer electronics; retain TLV2463IN for prototyping, repair, or high-reliability through-hole deployments. |
| TLV2772CDR | Higher 5.1-MHz GBW but lower 6-mA output drive; 10.5 V/µs slew rate; no shutdown pin; 360 µV VIO. | Optimized for AC-coupled audio or fast-settling filters; unsuitable for DC-precision or power-gated systems. | Choose TLV2772CDR only when speed outweighs DC accuracy and power gating - not a functional replacement for TLV2463IN in sensor front-ends. |
Compared with TLV2463IDR, TLV2463IN offers easier manual rework and higher mechanical reliability in vibration-prone environments; versus TLV2772CDR, it provides essential shutdown control and 3.6× lower input offset for precision DC measurement chains.

FAQ
What is the operating temperature range for TLV2463IN?
The TLV2463IN is specified for operation from −40°C to 125°C, matching the "I" temperature grade. This rating is validated across all electrical parameters in the datasheet and qualifies the device for under-hood automotive and industrial control applications without derating. The plastic DIP (N) package maintains mechanical integrity across this full range.
Does TLV2463IN support true rail-to-rail input and output?
Yes, TLV2463IN supports rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 100 mV of each rail at light loads). This is confirmed in the "Common-mode input voltage range" and "Output voltage swing" specifications, enabling full utilization of 3.3-V or 5-V ADC reference voltages without external level-shifting circuitry.
How does the shutdown feature work on TLV2463IN?
The SHDN pin (Pin 6) is an active-high control: applying ≥2 V enables both amplifiers; pulling ≤0.7 V places both channels into ultralow-power shutdown mode (0.3 µA/channel) and forces their outputs into high-impedance state. This behavior is explicitly defined in the "Shutdown on/off voltage level" section of the datasheet and verified across temperature.
What is the maximum capacitive load TLV2463IN can drive stably?
TLV2463IN is internally compensated for unity-gain stability with up to 160 pF capacitive load, as confirmed in the "Operating Characteristics" table and Figure 36 (Phase margin vs. load capacitance). Driving larger loads requires external isolation resistors or careful layout to avoid peaking or oscillation - no external compensation is needed within this limit.
Is TLV2463IN pin-compatible with other TLV246x variants in the same package?
Yes, TLV2463IN shares identical pinout and footprint with all TLV246x devices in the 14-pin plastic DIP (N) package, including TLV2462IN and TLV2464IN. This allows direct substitution in existing designs when upgrading channel count or adding shutdown functionality - verified via the "TLV246x PACKAGE PINOUTS" diagram on page 4 of the datasheet.
