Product details
Overview
TLV2462CDR from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for low-power portable systems. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, and ±80 mA output drive at 500 µA/channel supply current, with 100 µV input offset voltage and 11 nV/√Hz input noise voltage. It serves as a precision buffer for analog-to-digital converters in battery-powered instrumentation.
For engineers reviewing the TLV2462CDR datasheet, TLV2462CDR pinout, TLV2462CDR application, or TLV2462CDR equivalent, key selection criteria include rail-to-rail output swing down to 100 mV from rails, micropower shutdown mode (0.3 µA/channel), extended common-mode input range beyond supply rails, and operation across 2.7–6 V single-supply or ±1.35–±3 V split-supply configurations.
Technical Context
The TLV2462CDR implements a CMOS input stage enabling 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). Its internal architecture supports stable unity-gain operation with 160 pF capacitive load and provides 45° phase margin at 5 V supply.
It features independent shutdown control per channel (SHDN pins), placing each amplifier in ultralow-current state (0.3 µA/channel) while forcing output into high-impedance mode. The device is specified for 0°C to 70°C operation (C-suffix) and qualified for industrial-grade reliability in TSSOP-8 packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.4 MHz - Enables stable closed-loop operation up to ~1 MHz with gain ≥6, suitable for anti-aliasing and signal conditioning filters. |
| Slew rate | 1.6 V/µs - Supports 100 kHz full-power bandwidth for 1 VPP signals, sufficient for audio and sensor front-end buffering. |
| Supply current per channel | 500 µA - Enables continuous operation in always-on sensor nodes with multi-year battery life at 3 V. |
| Input offset voltage | 100 µV - Delivers ≤0.01% gain error in 10 V full-scale precision measurement paths without trimming. |
| Rail-to-rail output | Swings within 100 mV of rails at ±10 mA - Maximizes dynamic range in 3.3 V ADC interfaces, preserving >97% of available voltage headroom. |
| Shutdown current | 0.3 µA/channel - Reduces system standby power by >99% versus active mode, critical for duty-cycled data acquisition. |
| Input noise voltage | 11 nV/√Hz at 1 kHz - Limits added noise to <1 µV RMS in 10 kHz bandwidth, preserving SNR in low-level transducer amplification. |
Pinout & Package
TSSOP-8 package (DGK suffix), 3.0 mm × 4.4 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail buffered signal; capable of sourcing/sinking ±80 mA at 5 V supply. |

| 4 (GND) | Analog ground reference | Common return for both channels and shutdown logic; requires low-impedance PCB connection to minimize noise coupling. |
| 5 (SHDN A) | Channel A shutdown control | Active-high digital input; drives amplifier into 0.3 µA quiescent state when pulled ≥2 V (VIH) above GND. |
| 6 (VDD+) | Positive supply rail | Accepts 2.7–6 V single supply or +VDD in split-supply; decoupling capacitor required within 5 mm. |
| 7 (OUT B) | Channel B output | Independent rail-to-rail output; electrically isolated from Channel A except via shared VDD and GND. |
| 8 (IN− B) | Channel B inverting input | Matches Pin 2 electrical characteristics; enables dual-channel synchronous signal processing without crosstalk. |

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 |
|---|---|---|---|
| TLV2462IDR | Wider operating temperature range (−40°C to 125°C); identical electrical specs and pinout. | Required for under-hood automotive or industrial control environments exceeding 70°C ambient. | Select TLV2462IDR when design must operate reliably at junction temperatures up to 125°C. |
| OPA2340UA | Lower input offset (50 µV max), higher GBW (10 MHz), but no shutdown function and 1.2 mA/channel supply current. | Better for high-precision, high-speed applications where power budget allows >2× current draw and shutdown is unnecessary. | Choose OPA2340UA only if 50 µV offset and 10 MHz bandwidth are mandatory and shutdown is not required. |
Compared with TLV2462IDR, the TLV2462CDR trades extended temperature capability for lower cost and qualification scope, while OPA2340UA sacrifices micropower operation and shutdown for enhanced DC precision and AC performance-making TLV2462CDR optimal for cost-sensitive, battery-powered portable systems requiring flexible power management.

FAQ
What is the maximum supply voltage for TLV2462CDR?
The absolute maximum supply voltage for TLV2462CDR is 6 V. Operating continuously above this level risks permanent damage. The recommended operating range is 2.7 V to 6 V for single-supply use or ±1.35 V to ±3 V for split-supply configurations. At 5 V supply, TLV2462CDR delivers its full ±80 mA output drive capability and 1.6 V/µs slew rate as specified in the datasheet.
Does TLV2462CDR support true rail-to-rail input and output?
Yes, TLV2462CDR supports true rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 100 mV of VDD and GND at ±10 mA load). This capability is confirmed in the datasheet's Electrical Characteristics tables for both 3 V and 5 V supplies, enabling direct interfacing with 3.3 V ADCs without level-shifting circuitry.
How does the shutdown feature work on TLV2462CDR?
The TLV2462CDR has dedicated SHDN pins (Pin 5 for Channel A, Pin 8 for Channel B) that enable independent per-channel shutdown. When SHDN is pulled ≥2 V above GND (VIH), the corresponding amplifier enters ultralow-current mode (0.3 µA/channel) and its output transitions to high-impedance state. Pulling SHDN ≤0.7 V (VIL) returns the channel to normal operation. Both channels can be controlled simultaneously or separately.
What is the input offset voltage specification for TLV2462CDR?
The input offset voltage for TLV2462CDR is 100 µV (typical) and 2000 µV (maximum) at 25°C, with a maximum of 2200 µV across the full 0°C to 70°C operating range. This value is measured under standard test conditions (VDD = 3 V or 5 V, VIC = VDD/2, VO = VDD/2) and reflects the device's C-suffix commercial-grade tolerance, making it suitable for medium-precision signal conditioning tasks.
Which package type does TLV2462CDR use, and what are its key mechanical features?
TLV2462CDR uses the TSSOP-8 (DGK) package: 3.0 mm × 4.4 mm body size, 0.65 mm lead pitch, and an exposed thermal pad (non-functional, not electrically connected). This surface-mount package supports automated assembly and provides improved thermal performance over SOIC-8, with JEDEC-standard footprint compatibility and RoHS compliance.
