Product details
Overview
TLV2463CDGS from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier with shutdown control, 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 analog-to-digital converters in battery-powered systems.
For engineers reviewing the TLV2463CDGS datasheet, TLV2463CDGS pinout, TLV2463CDGS application, or TLV2463CDGS equivalent, this device is selected for precision, low-voltage operation (2.7–6 V), rail-to-rail dynamic range, micropower shutdown (0.3 µA/channel), and MSOP-10 packaging suitable for space-constrained mixed-signal PCB layouts.
Technical Context
The TLV2463CDGS integrates two independent amplifiers sharing a common shutdown terminal, supporting independent channel enable/disable sequencing. Its rail-to-rail input stage uses complementary differential pairs to extend common-mode range beyond supply rails (0 V to VDD), while the output stage employs Class AB push-pull architecture delivering ±80 mA into loads at full rail swing.
Shutdown functionality asserts high-impedance output state and reduces per-channel quiescent current to 0.3 µA - verified at VDD = 3–5 V and TA = −40°C to 125°C. The device maintains stable unity-gain operation with ≥44° phase margin driving up to 160 pF capacitive load, per TI SLOS220J Rev FEBRUARY 2004.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports closed-loop bandwidth up to ~5.2 MHz at AV = 1 with 160 pF load, suitable for anti-aliasing and sensor signal conditioning. |
| Slew Rate | 1.6 V/µs - enables clean 10 kHz sine-wave reproduction at 2 VPP without distortion in unity-gain buffer configurations. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.002% gain error in 5 V full-scale instrumentation amplifier front-ends. |
| Supply Current / Channel | 500 µA - allows continuous operation for >1 year on a single CR2032 coin cell in always-on sensor nodes. |
| Output Drive | ±80 mA - directly drives 62 Ω loads (e.g., 50 Ω coax + termination) without external buffers in data acquisition interfaces. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% versus active mode, critical for duty-cycled IoT endpoints. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - preserves SNR in 24-bit ADC front-ends with <1 LSB noise contribution over 10 Hz–100 kHz band. |
Pinout & Package
TLV2463CDGS is housed in a 10-pin MSOP (DGS) package with 0.5 mm pitch, 3.0 mm × 3.0 mm body, and exposed thermal pad (not electrically connected). Pin 1 is marked by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Delivers rail-to-rail voltage swing; high-impedance when SHDN = low. |
| 2 (IN− A) | Inverting input A | Differential node for A channel; supports common-mode range 0 V to VDD. |
| 3 (IN+ A) | Non-inverting input A | Differential node for A channel; matched bias current to IN− A. |
| 4 (GND) | Analog ground reference | Common return for both amplifiers and shutdown logic; must be low-impedance. |
| 5 (SHDN) | Active-low shutdown control | Pulls below 0.7 V to disable both amplifiers; >2 V to enable; CMOS-compatible. |
| 6 (VDD+) | Positive supply rail | Accepts 2.7–6 V single supply or ±1.35–±3 V split supply; bypass with 0.1 µF ceramic. |
| 7 (OUT B) | Amplifier B output | Independent rail-to-rail output; high-Z during shutdown, same drive capability as OUT A. |
| 8 (IN− B) | Inverting input B | Matches IN− A electrical characteristics; isolated from A channel except via shared GND/VDD. |
| 9 (IN+ B) | Non-inverting input B | Matches IN+ A; enables dual-channel simultaneous sampling in multi-sensor systems. |
| 10 (NC) | No internal connection | Unbonded pad; must remain unconnected or grounded only if required by PCB thermal relief. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode extends 200 mV beyond rails; output swings within 100 mV of rails at ±10 mA - maximizes dynamic range in 3.3 V systems. |
| Micropower shutdown | 0.3 µA/channel quiescent current in shutdown - enables ultra-low-power wake-on-event architectures with microcontroller GPIO control. |
| High-output drive | ±80 mA sourcing/sinking capability - eliminates need for external driver stages when interfacing with SAR ADC references or DAC buffers. |
| Low input offset voltage | 100 µV typical (1500 µV max over −40°C to 125°C) - reduces calibration overhead in precision weigh-scale and medical sensor front-ends. |
| Wide temperature range | Specified for −40°C to 125°C (I-suffix) - qualified for under-hood automotive and industrial motor control applications. |
| Stable capacitive loading | Phase margin ≥44° with 160 pF load - supports direct connection to long traces or ADC input capacitance without isolation resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2463IDGS | Same electrical specs but rated for −40°C to 125°C (I-suffix); 1500 µV max VIO vs 2000 µV for C-suffix. | Required for automotive or extended-temperature industrial deployments where ambient exceeds 70°C. | Select TLV2463IDGS when operating above 70°C ambient or requiring AEC-Q100 alignment. |
| OPA2340UA | Higher GBW (10 MHz), lower noise (7 nV/√Hz), but no shutdown; 800 µA/channel supply current; SO-8 package. | Better for wideband sensor excitation or audio preamp; unsuitable where shutdown or MSOP-10 footprint is mandatory. | Choose OPA2340UA only if bandwidth/noise outweighs power savings and board area constraints. |
Compared with TLV2463CDGS, TLV2463IDGS offers guaranteed performance at higher temperatures but identical pinout and function, while OPA2340UA trades shutdown capability and compact packaging for enhanced AC performance - making TLV2463CDGS optimal for space- and power-constrained dual-channel precision buffering.

FAQ
What is the maximum supply voltage for TLV2463CDGS?
The absolute maximum supply voltage for TLV2463CDGS is 6 V. Operating beyond this risks permanent damage. Recommended operation is 2.7 V to 6 V single supply or ±1.35 V to ±3 V dual supply, as specified in the SLOS220J datasheet. Exceeding 6 V violates absolute maximum ratings and may degrade ESD protection structures.
Does TLV2463CDGS support true rail-to-rail input and output?
Yes, TLV2463CDGS supports true rail-to-rail input and output. Its input common-mode voltage range extends 200 mV beyond the supply rails (0 V to VDD), and its output swings within 100 mV of each rail at ±10 mA load. This is confirmed in the "Rail-to-Rail Output Swing" headline and electrical characteristics tables of the SLOS220J datasheet.
How does the shutdown feature operate on TLV2463CDGS?
The SHDN pin on TLV2463CDGS is an active-low control: pulling it below 0.7 V places both amplifiers in ultralow-current shutdown (0.3 µA/channel), forcing outputs into high-impedance state. Driving SHDN above 2 V enables normal operation. This behavior is validated across −40°C to 125°C and is electrically compatible with standard CMOS logic levels.
What is the thermal performance of TLV2463CDGS in MSOP-10 (DGS) package?
TLV2463CDGS in DGS package has θJA = 257.7°C/W and θJC = 54.1°C/W. At TA = 25°C, its maximum power dissipation is 485 mW; derating linearly to 97 mW at TA = 125°C. These values are published in the Dissipation Rating Table of SLOS220J and assume standard JEDEC 2-layer board layout with copper pour under the exposed pad.
Is TLV2463CDGS pin-compatible with other TLV246x variants in MSOP-10?
Yes, TLV2463CDGS shares identical pinout and footprint with TLV2463IDGS, TLV2463AQDGS, and TLV2463AIDGS - all MSOP-10 (DGS) packaged members of the TLV246x family. Pin assignments (including NC on pin 10) and electrical interface are fully consistent, enabling drop-in replacement across temperature grades without PCB revision.
