Product details
Overview
TLV2462AQPWR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier designed for automotive 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. Its Q-temp automotive qualification (−40°C to 125°C) and shutdown capability make it suitable for engine control sensor buffering and battery monitoring circuits.
For engineers reviewing the TLV2462AQPWR datasheet, TLV2462AQPWR pinout, TLV2462AQPWR application, or TLV2462AQPWR equivalent, key selection considerations include rail-to-rail I/O swing in low-voltage systems (2.7–6 V), micropower shutdown mode (0.3 µA/channel), input noise voltage (11 nV/√Hz at 1 kHz), and TSSOP-8 package compatibility with high-density PCB layouts.
Technical Context
The TLV2462AQPWR implements a CMOS input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing within 10 mV of each rail. Its internal architecture supports stable unity-gain operation with 45° phase margin at 10 kΩ load and 160 pF capacitive load.
It features an active-low shutdown terminal (SHDN) that places both amplifiers into ultralow-current state (0.3 µA/channel) while forcing outputs to high-impedance. The device maintains DC precision across temperature (±2 µV/°C offset drift) and exhibits 85 dB supply voltage rejection ratio at 2.7–6 V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - Enables stable closed-loop operation up to ~1 MHz with moderate gain (e.g., G = 5). |
| Slew Rate | 1.6 V/µs - Supports 100 kHz full-power sine wave output at 1 VPP without distortion. |
| Input Offset Voltage | 100 µV (typ) - Ensures <0.01% error in 1 V reference buffer or 10-bit ADC front-end applications. |
| Supply Current per Channel | 500 µA - Allows dual op-amp operation from coin-cell or low-quiescent power rails. |
| Rail-to-Rail I/O | Input: 0 V to VDD; Output: within 10 mV of rails - Maximizes dynamic range in 3.3 V or 5 V single-supply systems. |
| Shutdown Current | 0.3 µA/channel - Reduces system standby power by >99% vs active mode; output enters high-Z state. |
| Operating Temperature | −40°C to 125°C - Qualified per AEC-Q100 for under-hood automotive use and industrial control environments. |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 4.4 mm, 0.65 mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail buffered signal; capable of ±80 mA sourcing/sinking at 5 V supply. |
| 2 (IN− A) | Channel A inverting input | High-impedance CMOS node; bias current ≤75 nA over full temperature range. |
| 3 (IN+ A) | Channel A non-inverting input | Supports common-mode voltage from ground to VDD; enables single-supply sensor interface. |
| 4 (GND) | Analog ground reference | Common return for both channels; must be low-impedance path to minimize noise coupling. |
| 5 (SHDN) | Active-low shutdown control | Pull ≤0.7 V to disable both amps; pull ≥2 V to enable; no external pull-up required. |
| 6 (IN+ B) | Channel B non-inverting input | Independent input for second channel; identical specs and rail-to-rail support as Channel A. |
| 7 (IN− B) | Channel B inverting input | Matches Channel A performance; allows dual independent gain stages or differential pair configuration. |
| 8 (OUT B) | Channel B output | Functionally identical to OUT A; supports independent loading and output routing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 2.7–6 V supply range in single-supply data acquisition systems. |
| Micropower shutdown mode | Reduces total quiescent current to 0.6 µA (both channels), critical for battery-powered wake-on-event designs. |
| Low input noise voltage | 11 nV/√Hz at 1 kHz - preserves SNR in precision sensor amplification (e.g., thermocouple, strain gauge). |
| High output drive capability | ±80 mA at 5 V - directly drives 60 Ω loads or multiple inputs without external buffers. |

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 |
|---|---|---|---|
| TLV2462IPW | Same silicon, commercial temp range (−40°C to 85°C), non-automotive qualified. | Lacks AEC-Q100 qualification; unsuitable for under-hood automotive use. | Select TLV2462IPW only for cost-sensitive industrial or consumer applications where extended temperature and automotive reliability are not required. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs TLV2462AQPWR's 2 µV/°C; higher 350 µA/channel supply current. | Better DC stability for long-term sensor calibration; higher power consumption limits battery life. | Choose OPA2333AIDR when ultra-low drift dominates over power budget; TLV2462AQPWR remains optimal for balanced AC/DC performance in automotive systems. |
Compared with TLV2462IPW, TLV2462AQPWR adds automotive qualification and extended temperature operation but shares identical electrical specs and pinout; versus OPA2333AIDR, TLV2462AQPWR trades zero-drift precision for lower quiescent current and broader supply range (2.7–6 V vs 1.8–5.5 V), making it more suitable for 5 V automotive domains.

FAQ
What is the operating temperature range for TLV2462AQPWR?
The TLV2462AQPWR is qualified for −40°C to 125°C operation per AEC-Q100 Grade 2 requirements. This extended range supports deployment in under-hood automotive environments, industrial control cabinets, and outdoor equipment where ambient temperatures exceed standard commercial limits. All electrical specifications-including input offset voltage, supply current, and gain bandwidth-are guaranteed across this full range.
Does TLV2462AQPWR support true rail-to-rail input and output?
Yes, TLV2462AQPWR provides true rail-to-rail input (common-mode range from GND to VDD) and rail-to-rail output (swing within 10 mV of each rail at light load). This capability is confirmed in the datasheet's "Recommended Operating Conditions" and "Electrical Characteristics" tables for both 3 V and 5 V supplies, enabling full dynamic range utilization in single-supply systems such as 3.3 V microcontroller interfaces.
How does the shutdown function work on TLV2462AQPWR?
The SHDN pin (Pin 5) is active-low: driving it ≤0.7 V disables both amplifiers, reducing total supply current to 0.6 µA (0.3 µA per channel) and placing both outputs in high-impedance state. Driving SHDN ≥2 V enables normal operation. No external pull-up resistor is required, and the transition times (ton = 7.65 µs, toff = 328 ns) support fast wake-up in responsive sensor systems.
What package type is used for TLV2462AQPWR?
TLV2462AQPWR uses the TSSOP-8 (PW) package: 3.0 mm × 4.4 mm body size, 0.65 mm lead pitch, with an exposed thermal pad (non-connected). This RoHS-compliant, surface-mount package supports high-density PCB layouts and meets automotive reflow profile requirements. Pinout matches industry-standard dual op-amp configurations, simplifying layout reuse.
Can TLV2462AQPWR drive heavy capacitive loads?
TLV2462AQPWR is stable with up to 160 pF capacitive load at unity gain (per datasheet Figure 36), delivering 45° phase margin. For heavier loads (>200 pF), external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to maintain stability. The device's 33 Ω closed-loop output impedance at 100 kHz further supports direct driving of moderate capacitive nodes like ADC sample capacitors.
