Product details
Overview
TLV2463CDR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized 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 SAR ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLV2463CDR datasheet, TLV2463CDR pinout, TLV2463CDR application, or TLV2463CDR equivalent, key selection considerations include its shutdown capability (0.3 µA/channel), extended −40°C to 125°C operating range, MSOP-8 package footprint, and rail-to-rail dynamic range at 2.7–6 V supply - critical for precision analog interfaces in automotive body control modules and industrial PLC I/O stages.
Technical Context
The TLV2463CDR implements a complementary input stage enabling true rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing. Its internal architecture supports stable operation with capacitive loads up to 160 pF while maintaining ≥44° phase margin at unity gain.
It integrates independent shutdown control per channel (SHDN pins 1 and 8), placing each amplifier into ultralow-current mode (0.3 µA/channel) with high-impedance output - preserving system-level power sequencing integrity without external isolation circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop gain ≥10 at 640 kHz for anti-aliasing filter drivers |
| Slew Rate | 1.6 V/µs - supports 12-bit settling within 1 µs for 2-Vpp signals in ADC buffer applications |
| Supply Current / Channel | 500 µA - allows dual op-amp operation under 1 mA total, suitable for always-on sensor nodes |
| Input Offset Voltage | 100 µV - ensures ≤0.0025% gain error in 4–20 mA transmitter current-sense amplifiers |
| Output Drive | ±80 mA - drives 50 Ω transmission lines or multiple 10 kΩ ADC inputs without external buffers |
| Rail-to-Rail I/O | Input: 0 V to VDD; Output: within 100 mV of rails - maximizes dynamic range in 3.3 V single-supply systems |
| Shutdown Current / Channel | 0.3 µA - reduces standby power to <1 µA for dual-channel configuration in wake-on-event designs |
Pinout & Package
TLV2463CDR is packaged in an 8-pin MSOP (DGS) with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm - compatible with automated SMT assembly and offering improved thermal performance over SOIC-8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN A) | Channel A shutdown control | Logic-high (>2 V) enables Channel A; logic-low (<0.7 V) disables it with high-Z output |
| 2 (IN− A) | Inverting input, Channel A | Differential input node accepting rail-to-rail common-mode voltage (0 V to VDD) |
| 3 (IN+ A) | Non-inverting input, Channel A | High-impedance input (1300 pA bias) for precision voltage sensing |
| 4 (GND) | Analog ground reference | Common return path for both channels; requires low-impedance PCB plane connection |
| 5 (OUT A) | Amplifier A output | Capable of sourcing/sinking ±80 mA while maintaining rail-to-rail swing |
| 6 (OUT B) | Amplifier B output | Independent output with identical drive and swing specs as OUT A |
| 7 (IN+ B) | Non-inverting input, Channel B | Electrically isolated from Channel A inputs; supports dual-sensor signal conditioning |
| 8 (SHDN B) | Channel B shutdown control | Independent logic-controlled disable; no cross-talk with Channel A operation |
Key Features

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 electrical specs but rated for −40°C to 125°C (I-suffix); higher VIOmax (1500 µV vs. 2000 µV) | Required for automotive under-hood or industrial control cabinet deployments beyond 70°C ambient | Select TLV2463IDR when extended temperature qualification and tighter VIO distribution are mandatory |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C drift vs. TLV2463CDR's 2 µV/°C; higher supply current (17 µA/ch) | Preferred for DC-critical applications like precision weight scales where long-term offset stability dominates | Choose OPA2333AIDR only when sub-µV drift over time/temperature outweighs 34× higher quiescent power |
Compared with TLV2463IDR, the TLV2463CDR trades extended temperature rating for lower cost and wider availability in commercial-grade applications; versus OPA2333AIDR, it offers 34× lower supply current but lacks zero-drift correction - making it optimal for AC-coupled or moderate-DC-accuracy portable signal chains.

FAQ
What is the operating temperature range for TLV2463CDR?
The TLV2463CDR is specified for 0°C to 70°C ambient operation (C-suffix grade). Its electrical characteristics - including input offset voltage, supply current, and gain-bandwidth product - are guaranteed across this range per the SLOS220J datasheet. For extended temperature applications, TI offers the TLV2463IDR (−40°C to 125°C).
Does TLV2463CDR support single-supply operation?
Yes, TLV2463CDR supports true single-supply operation from 2.7 V to 6 V. Its rail-to-rail input stage accepts common-mode voltages from 0 V to VDD, and its output swings within 100 mV of both rails - enabling direct interfacing with 3.3 V or 5 V microcontrollers and ADCs without level-shifting components.
How does the shutdown function work on TLV2463CDR?
TLV2463CDR features independent shutdown control on Pins 1 (SHDN A) and 8 (SHDN B). Driving either pin below 0.7 V places the corresponding amplifier channel into ultralow-current mode (0.3 µA/channel), disabling output stage and forcing high-impedance output. Both channels remain fully functional when pins are held above 2 V.
What is the maximum capacitive load TLV2463CDR can drive stably?
TLV2463CDR maintains ≥44° phase margin with up to 160 pF capacitive load at unity gain (RL = 10 kΩ), as verified in the SLOS220J datasheet Figure 36. For loads exceeding 160 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to preserve stability in ADC driver or cable-driving configurations.
Is TLV2463CDR pin-compatible with other TLV246x variants?
TLV2463CDR (MSOP-8, DGS package) shares identical pinout with TLV2463IDR, TLV2463AIDR, and all TLV2463x variants in the DGS package. However, it is not pin-compatible with TLV2463CD (SOIC-8) or TLV2463CN (PDIP-14) due to differing package footprints and terminal assignments.
