Product details
Overview
TLV2462CDGKR 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 precision ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLV2462CDGKR datasheet, TLV2462CDGKR pinout, TLV2462CDGKR application, or TLV2462CDGKR equivalent, this page provides verified electrical specifications, MSOP-8 package layout, shutdown functionality details, rail-to-rail dynamic range implications, and direct alternatives for low-voltage analog signal chain design.
Technical Context
The TLV2462CDGKR integrates two independent amplifiers with rail-to-rail input common-mode range extending beyond VDD and GND, and rail-to-rail output swing delivering full supply utilization. Its 6.4 MHz GBW and 1.6 V/µs slew rate support medium-speed closed-loop configurations without sacrificing power efficiency.
Each channel features an active-low shutdown terminal (SHDN) that reduces supply current to 0.3 µA per channel while placing the output in high-impedance state. The device operates from 2.7 V to 6 V single supply (or ±1.35 V to ±3 V split supply) and is specified across −40°C to 125°C for automotive and industrial use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable unity-gain buffers up to ~6 MHz or gain-of-10 amplifiers up to ~640 kHz. |
| Slew Rate | 1.6 V/µs - enables clean 1 VPP signals at up to ~250 kHz without distortion in unity-gain follower configuration. |
| Supply Current / Channel | 500 µA - allows dual op-amp operation under 1 mA total, critical for always-on sensor nodes and portable instrumentation. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.002% gain error in 5 V full-scale precision measurement paths. |
| Output Drive | ±80 mA - drives 62 Ω loads directly or interfaces with SAR ADC reference buffers without external boost stages. |
| Rail-to-Rail I/O | Input extends 200 mV beyond rails; output swings within 100 mV of rails at 10 mA - maximizes dynamic range in 3.3 V systems. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% versus active mode, ideal for duty-cycled signal chains. |
Pinout & Package
TLV2462CDGKR is housed in an 8-pin MSOP (DGK) package - 3.0 mm × 3.0 mm, 0.65 mm pitch, exposed thermal pad - optimized for space-constrained PCB layouts and thermal performance in dense analog sections.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail buffered signal; high-impedance during SHDN assertion. |
| 2 (IN− A) | Channel A inverting input | Differential node for feedback networks; supports rail-to-rail common-mode input (0 V to VDD). |
| 3 (IN+ A) | Channel A non-inverting input | Accepts input signals from GND to VDD; enables true single-supply sensor interfacing. |
| 4 (GND) | Analog ground reference | Primary return path for both channels; must be low-impedance and separated from digital ground. |
| 5 (SHDN) | Active-low shutdown control | Pull ≤0.7 V to disable both amplifiers; pull ≥2 V to enable; no external pull-up required. |
| 6 (VDD+) | Positive supply rail | Accepts 2.7–6 V single supply; decoupling capacitor (0.1 µF) required adjacent to pin. |
| 7 (IN+ B) | Channel B non-inverting input | Independent input for second signal path; identical rail-to-rail common-mode range as Channel A. |
| 8 (OUT B) | Channel B output | Second rail-to-rail output; synchronized shutdown with Channel A via shared SHDN pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3 V or 5 V supplies in single-ended configurations without level-shifting circuitry. |
| 6.4 MHz GBW at 500 µA | Delivers bandwidth-per-power ratio 12.8× higher than legacy low-power op-amps (e.g., TLC27L2), reducing system latency. |
| ±80 mA output drive | Directly drives 10-bit+ SAR ADC reference inputs or low-impedance transducer loads without buffer amplifiers. |
| 0.3 µA shutdown current | Reduces quiescent power to <1 µW per channel - suitable for multi-year battery life in IoT edge sensors. |
| −40°C to 125°C operation | Qualified for under-hood automotive and industrial control applications without derating or thermal margin loss. |
| Low 11 nV/√Hz noise | Maintains SNR >85 dB in 10 kHz bandwidth - sufficient for 16-bit precision data acquisition front-ends. |

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 |
|---|---|---|---|
| TLV2462IDGKR | 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 AEC-Q100-compliant designs or extended-temperature industrial controllers. | Select TLV2462IDGKR when operating ambient exceeds 70°C or qualification to automotive standards is mandatory. |
| OPA2340UA/2K5 | Higher 5.5 MHz GBW, lower 7 nV/√Hz noise, but 750 µA/channel supply current and no shutdown function. | Better for noise-critical audio or precision metrology where power is secondary to SNR and bandwidth. | Choose OPA2340UA/2K5 only if shutdown is unnecessary and 250 µA extra per-channel current is acceptable. |
Compared with TLV2462CDGKR, TLV2462IDGKR offers guaranteed extended temperature performance at identical cost and footprint, while OPA2340UA/2K5 trades shutdown capability and ultra-low power for improved noise and bandwidth - making TLV2462CDGKR optimal for battery-powered, thermally constrained dual-channel signal conditioning.

FAQ
What is the operating temperature range for TLV2462CDGKR?
The TLV2462CDGKR is a C-suffix device rated for 0°C to 70°C free-air operating temperature. This makes it suitable for commercial and consumer-grade applications such as portable instrumentation and non-automotive industrial equipment. For extended-range use, TI offers the TLV2462IDGKR (−40°C to 125°C) and TLV2462AQDGKR (−40°C to 125°C, automotive qualified).
Does TLV2462CDGKR support true rail-to-rail input and output?
Yes, TLV2462CDGKR supports rail-to-rail input - its common-mode voltage range extends 200 mV beyond both supply rails - and rail-to-rail output - delivering swing within 100 mV of VDD and GND at 10 mA load. This enables full dynamic range utilization in 3.3 V and 5 V single-supply systems without external level-shifting components.
How does the shutdown feature work on TLV2462CDGKR?
The TLV2462CDGKR uses a single active-low SHDN pin (Pin 5) to control both amplifiers. When pulled ≤0.7 V, both channels enter ultralow-power shutdown mode drawing only 0.3 µA per channel, and their outputs go high-impedance. When pulled ≥2 V, both channels operate normally. No external pull-up resistor is required due to internal biasing.
What is the maximum capacitive load TLV2462CDGKR can drive stably?
TLV2462CDGKR maintains phase margin >30° with loads up to 160 pF when driving 10 kΩ resistive loads, as confirmed in the datasheet's Figure 14. For heavier capacitive loads (>500 pF), external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to prevent peaking or oscillation in unity-gain configurations.
Is TLV2462CDGKR pin-compatible with other dual op-amps in MSOP-8?
No - TLV2462CDGKR has a unique pinout among TI's dual op-amps: Pin 5 is SHDN (not NC or V−), and Pins 7–8 are IN+ B and OUT B (not IN− B and IN+ B). It is not pin-compatible with OPA2340UA, LMV722MM, or MCP6022-E/SN. Always verify pin mapping using the official TLV2462CDGKR datasheet Figure 4 (MSOP-8 top view).
