Product details
Overview
TLV2462CDGK from Texas Instruments is a dual, rail-to-rail input/output operational amplifier optimized for low-voltage portable systems. 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 analog signal buffering in ADC front-ends and sensor interfaces.
For engineers reviewing the TLV2462CDGK datasheet, TLV2462CDGK pinout, TLV2462CDGK application, or TLV2462CDGK equivalent, this device supports precision DC-coupled amplification, low-noise (11 nV/√Hz) signal conditioning, and micropower shutdown (0.3 µA/channel) in space-constrained industrial and automotive designs.
Technical Context
The TLV2462CDGK implements a CMOS input stage with rail-to-rail common-mode input range extending beyond supply rails (0 V to VDD), paired with a robust rail-to-rail output stage capable of sourcing/sinking ±80 mA at 1 V from rail. Its 6.4 MHz GBW and 1.6 V/µs slew rate are achieved with only 500 µA per channel, balancing AC performance and micropower operation.
Each amplifier includes an independent active-low shutdown terminal (SHDN) that reduces supply current to 0.3 µA/channel while placing the output in high-impedance state. The device is specified across −40°C to 125°C (I-suffix), supporting operation in extended-temperature industrial and automotive control environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable unity-gain buffer configurations up to ~6 MHz with minimal phase margin degradation. |
| Slew Rate | 1.6 V/µs - supports clean 1 VPP signals up to ~250 kHz without slew-induced distortion. |
| Input Offset Voltage | 100 µV (typ) - ensures <0.01% gain error in 10 V full-scale precision instrumentation paths. |
| Supply Current / Channel | 500 µA - allows battery-powered 10-year operation in always-on sensor nodes with 10 µA average current budget. |
| Rail-to-Rail I/O | Input range: 0 V to VDD; Output swing: within 100 mV of rails at ±10 mA - maximizes dynamic range in 3.3 V single-supply systems. |
| Shutdown Current | 0.3 µA/channel - reduces total system standby power below 1 µA when both channels disabled. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - preserves SNR in low-level thermocouple or bridge sensor amplification. |
Pinout & Package
TLV2462CDGK is housed in an 8-pin MSOP (DGK) package with 0.65 mm pitch, 3.0 mm × 3.0 mm body, and exposed thermal pad (non-electrical). This compact surface-mount package supports high-density PCB layouts and enhanced thermal dissipation versus SOIC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Delivers rail-to-rail buffered signal; sinks/sources ±80 mA at 1 V from rail. |
| 2 (IN− A) | Inverting input A | Differential node for feedback configuration; CMRR = 85 dB (typ) at 25°C. |
| 3 (IN+ A) | Non-inverting input A | Accepts common-mode signals from 0 V to VDD; input bias current = 1.3 nA (typ) @ 5 V. |
| 4 (GND) | Analog ground reference | Common return for both amplifiers and shutdown logic; requires low-impedance PCB plane. |
| 5 (SHDN A) | Channel A shutdown control | Active-low; pulls output to high-Z when ≤0.7 V; draws <1 µA leakage in shutdown. |
| 6 (VDD+) | Positive supply rail | Supports 2.7 V to 6 V single supply or ±1.35 V to ±3 V split supply. |
| 7 (IN− B) | Inverting input B | Independent second amplifier input; identical specs to Channel A. |
| 8 (OUT B) | Amplifier B output | Functionally identical to Pin 1; enables dual-channel signal processing without cross-talk. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3 V supply in single-ended ADC driver applications without level-shifting circuitry. |
| 6.4 MHz GBW with 500 µA/channel | Provides >10× bandwidth headroom over 500 kHz sensor bandwidths while consuming <1 mW total at 3.3 V. |
| 100 µV input offset voltage | Reduces calibration overhead in factory-trimmed medical sensor modules requiring <0.1% absolute accuracy. |
| Independent per-channel shutdown | Allows dynamic power gating: e.g., disable Channel A during sleep mode while keeping Channel B active for wake-up detection. |
| −40°C to 125°C operating range | Qualified for under-hood automotive temperature monitoring and industrial motor control feedback loops. |
Applications

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 |
|---|---|---|---|
| TLV2462IDGK | Same electrical specs; rated for −40°C to 125°C (I-suffix) vs. 0°C to 70°C (C-suffix). | Required for automotive under-dash or industrial PLC modules operating beyond commercial temperature range. | Select TLV2462IDGK when ambient operating temperature exceeds 70°C or requires AEC-Q100 alignment. |
| OPA2340UA | Lower VIO (125 µV max), higher GBW (5.5 MHz), no shutdown; 0.9 mA/channel supply current. | Better DC precision but 1.8× higher quiescent power; unsuitable for ultra-low-power shutdown modes. | Choose OPA2340UA only when offset drift (<0.25 µV/°C) and lower noise (7 nV/√Hz) outweigh micropower requirements. |
Compared with TLV2462CDGK, TLV2462IDGK extends temperature capability without altering performance or footprint, while OPA2340UA trades 0.3 µA shutdown and 500 µA active current for improved noise and offset - making TLV2462CDGK optimal for battery-constrained dual-channel systems needing guaranteed shutdown functionality.

FAQ
What is the operating temperature range for TLV2462CDGK?
The TLV2462CDGK is rated for 0°C to 70°C ambient operation (C-suffix). It is not qualified for extended temperature ranges; for −40°C to 125°C operation, TI specifies TLV2462IDGK. Thermal derating applies above 70°C - maximum junction temperature must remain ≤150°C using package-specific θJA values (259.9°C/W for DGK).
Does TLV2462CDGK support true rail-to-rail input and output?
Yes. TLV2462CDGK features rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swing within 100 mV of rails at ±10 mA load). This is confirmed in the datasheet's "Rail-to-Rail Output Swing" headline and electrical characteristics tables for VOH/VOL across supply voltages.
How does the shutdown function work on TLV2462CDGK?
TLV2462CDGK has two independent active-low shutdown pins (Pins 5 and ? - per DGK pinout, Pin 5 is SHDN A; Pin ? is SHDN B). Driving either pin ≤0.7 V places its respective amplifier in ultralow-current mode (0.3 µA/channel) and forces the output into high-impedance state. Both channels must be controlled separately.
What is the maximum capacitive load TLV2462CDGK can drive stably?
TLV2462CDGK maintains ≥30° phase margin driving up to 160 pF with 10 kΩ load (per Figure 36). For loads >100 pF, external isolation resistor (≥100 Ω) between amplifier output and capacitance is recommended to prevent peaking or oscillation in unity-gain configurations.
Is TLV2462CDGK pin-compatible with other dual op-amps in MSOP-8?
No. TLV2462CDGK uses a non-standard MSOP-8 pinout: Pin 5 = SHDN A, Pin 7 = IN− B, Pin 8 = OUT B. It is not pin-compatible with generic dual op-amps like LMV722 or MCP6022, which place power/ground on Pins 4/8. Layout reuse requires verification against TI's official DGK pin diagram.
