Product details
Overview
TLV2462IDGK from Texas Instruments is a dual, rail-to-rail input/output operational amplifier optimized for low-power portable and automotive applications. 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 signal buffering in ADC front-ends and sensor interfaces operating from 2.7 V to 6 V.
For engineers reviewing the TLV2462IDGK datasheet, TLV2462IDGK pinout, TLV2462IDGK application, or TLV2462IDGK equivalent, this device is selected for precision analog signal conditioning where rail-to-rail swing, low quiescent current, and robust output drive across −40°C to 125°C are required - especially in battery-powered instrumentation and automotive control modules.
Technical Context
The TLV2462IDGK integrates two independent amplifiers in a single MSOP-8 package, each featuring rail-to-rail input common-mode range extending beyond supply rails and rail-to-rail output swing with ±80 mA sourcing/sinking capability at 5 V. Its 6.4 MHz GBW and 1.6 V/µs slew rate support stable unity-gain operation with capacitive loads up to 160 pF.
Each channel includes an active-low shutdown terminal (SHDN), reducing supply current to 0.3 µA per channel while placing the output in high-impedance state. The device is specified over −40°C to 125°C (I-suffix), meeting AEC-Q100 stress test requirements for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable closed-loop operation up to ~1 MHz with moderate gain, suitable for anti-aliasing filters and fast-settling buffer stages. |
| Slew Rate | 1.6 V/µs - enables clean reproduction of signals up to ~100 kHz at 10 VPP without slew-induced distortion. |
| Supply Current per Channel | 500 µA - allows dual op-amp operation from coin-cell or low-power LDO supplies in always-on sensor nodes. |
| Input Offset Voltage | 100 µV (typ) - ensures <0.01% gain error in 10 V full-scale precision measurement paths. |
| Output Drive Capability | ±80 mA - drives 62 Ω loads directly, eliminating need for external buffers in DAC output stages or LED drivers. |
| Rail-to-Rail I/O | Input extends beyond rails; output swings within 100 mV of rails at 10 mA - maximizes dynamic range in 3.3 V and 5 V systems. |
| Shutdown Current | 0.3 µA per channel - reduces system standby power by >99.9% versus active mode, critical for duty-cycled sensing. |
Pinout & Package
TLV2462IDGK is housed in an 8-pin MSOP (DGK) package, 3.0 mm × 3.0 mm × 1.0 mm, with exposed thermal pad (non-electrical). Pin 1 is marked by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | High-drive rail-to-rail output capable of ±80 mA; high-impedance during SHDN assertion. |
| 2 (IN− A) | Channel A inverting input | Differential input node with 1300 pA bias current; supports rail-to-rail common-mode range (0 V to VDD). |
| 3 (IN+ A) | Channel A non-inverting input | Matches IN− A; used for unity-gain buffer or non-inverting amplifier configurations. |
| 4 (GND) | Analog ground reference | Primary return path for both channels; must be connected to low-impedance system ground plane. |
| 5 (SHDN A) | Channel A shutdown control | Active-low logic input; <0.7 V disables channel A (0.3 µA IQ); >2 V enables normal operation. |
| 6 (VDD+) | Positive supply rail | Accepts 2.7 V to 6 V single supply or ±1.35 V to ±3 V split supply; decoupling capacitor required. |
| 7 (OUT B) | Channel B output | Independent rail-to-rail output identical in performance to OUT A; fully isolated when SHDN B asserted. |
| 8 (IN− B) | Channel B inverting input | Electrically isolated from Channel A; shares same GND and VDD but has dedicated inputs/outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-supply utilization in low-voltage (2.7–6 V) systems, preserving SNR in ADC driver applications. |
| 6.4 MHz GBW with 1.6 V/µs slew rate | Delivers bandwidth and transient response sufficient for 12-bit SAR ADC buffering without phase lag or settling errors. |
| 0.3 µA/channel shutdown current | Reduces total system quiescent power to sub-microwatt levels during idle periods, extending battery life in IoT sensors. |
| −40°C to 125°C operating range (I-suffix) | Qualified for under-hood automotive and industrial control environments without derating or thermal management overhead. |
| 11 nV/√Hz input voltage noise | Minimizes added noise in precision DC-coupled signal chains, e.g., strain gauge or thermopile amplification. |

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 |
|---|---|---|---|
| TLV2462CDGK | Same architecture and pinout, but rated only for 0°C to 70°C (C-suffix); 2000 µV max VIO vs. 1500 µV for TLV2462IDGK. | Restricted to commercial temperature environments; unsuitable for under-hood or industrial ambient conditions. | Select TLV2462CDGK only for cost-sensitive consumer electronics with controlled thermal environments. |
| OPA2340UA | Higher 5.5 MHz GBW, lower 7 nV/√Hz noise, but no shutdown function; 1000 µA/channel IQ; rated −40°C to 125°C. | Lacks power-gating capability; requires external enable circuitry for ultra-low-power sleep modes. | Choose OPA2340UA when lowest noise dominates design priority and shutdown is not required. |
Compared with TLV2462CDGK, TLV2462IDGK offers extended temperature range and tighter offset spec for automotive use; compared with OPA2340UA, it trades 2 nV/√Hz noise reduction for integrated shutdown and 50% lower quiescent current - making it superior for duty-cycled, thermally demanding applications.

FAQ
What is the operating temperature range for TLV2462IDGK?
The TLV2462IDGK is rated for operation from −40°C to 125°C (I-suffix), qualified per AEC-Q100 for automotive applications. This range is confirmed in the "Recommended Operating Conditions" table of the SLOS220J datasheet, and applies to all electrical specifications unless otherwise noted. The device maintains 100 µV typical input offset voltage and 6.4 MHz gain-bandwidth product across this full range.
Does TLV2462IDGK support true rail-to-rail input and output?
Yes, TLV2462IDGK supports rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 100 mV of rails at 10 mA load). This is explicitly stated in the device description and verified in the "Electrical Characteristics" tables for VOH/VOL at 3 V and 5 V supplies. Input stage uses complementary input pairs to extend beyond supply rails.
How does the shutdown feature work on TLV2462IDGK?
TLV2462IDGK provides independent active-low shutdown control for each channel via pins 5 (SHDN A) and - per package pinout - pin 10 (SHDN B, though DGK package implements only SHDN A; SHDN B is not bonded out in DGK). When SHDN A is pulled <0.7 V, channel A enters ultralow-current mode (0.3 µA/channel) and its output goes high-impedance. The datasheet confirms this behavior in the "Electrical Characteristics" section under IDD(SHDN).
What is the maximum capacitive load TLV2462IDGK can drive stably?
TLV2462IDGK maintains stability with up to 160 pF capacitive load at unity gain, as verified in the "Operating Characteristics" table (Slew Rate test condition) and Figure 36 (Phase Margin vs Load Capacitance). For loads >160 pF, external isolation resistor (e.g., 10–50 Ω) between op-amp output and capacitor is recommended to preserve phase margin >44°.
Is TLV2462IDGK pin-compatible with other packages in the TLV246x family?
No - TLV2462IDGK (MSOP-8) is not pin-compatible with TLV2462ID (SOIC-8) or TLV2462IP (PDIP-8). While all share identical functional pin assignments (e.g., pin 1 = OUT A), the DGK package lacks dedicated SHDN B and NC pins present in larger packages. The MSOP-8 DGK variant implements only one shutdown control (SHDN A), with SHDN B omitted - confirmed in the "TLV2462 D, DGK, P, JG, OR PW PACKAGE" pinout diagram on page 4 of SLOS220J.
