Product details
Overview
TLV2462AQDREP from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for low-power portable and precision analog signal conditioning. It delivers 6.4 MHz gain bandwidth, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage across −40°C to 125°C. It is used in ADC buffering, sensor front-ends, and battery-powered instrumentation.
For engineers reviewing the TLV2462AQDREP datasheet, TLV2462AQDREP pinout, TLV2462AQDREP application, or TLV2462AQDREP equivalent, this page provides verified specifications, D-package pin mapping, temperature-hardened performance data, shutdown functionality details, and validated alternative op-amps for design-in and sourcing decisions.
Technical Context
The TLV2462AQDREP implements a CMOS input stage enabling rail-to-rail common-mode input range (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing. Its 6.4 MHz unity-gain bandwidth and 1.6 V/µs slew rate support medium-speed signal conditioning without compromising power efficiency.
It integrates an active shutdown terminal (SHDN) that reduces per-channel supply current to 0.3 µA while placing the output in high-impedance state. The device is qualified for extended temperature operation (−40°C to 125°C) with JEDEC-compliant reliability testing including HAST, temperature cycling, and electromigration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - Enables stable unity-gain buffer or gain-of-10 amplification up to ~640 kHz. |
| Slew Rate | 1.6 V/µs - Supports 1-Vpp signals at up to ~250 kHz without slew-induced distortion. |
| Supply Current (per channel) | 500 µA - Enables dual-op-amp operation from coin-cell or single Li-ion sources. |
| Input Offset Voltage | 100 µV - Delivers <0.01% error in 1-V full-scale precision gain stages. |
| Rail-to-Rail I/O | Input range extends beyond rails; output swings within 100 mV of VDD/GND at 10 mA - maximizes dynamic range in 3.3-V or 5-V systems. |
| Shutdown Current | 0.3 µA/channel - Reduces system standby power by >99.9% versus active mode. |
| Output Drive | ±80 mA - Directly drives 50-Ω transmission lines or 100-mA loads without external buffers. |
Pinout & Package
TLV2462AQDREP is housed in an 8-pin SOIC (D) package with exposed pad (thermal enhancement), footprint-compatible with industry-standard SOIC-8 layouts. Pin 1 is marked with a dot or beveled edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | High-drive rail-to-rail output; sinks/sources ±80 mA; high-impedance during shutdown. |
| 1IN− | Channel 1 inverting input | Differential input node; supports common-mode range from −0.2 V to VDD + 0.2 V. |
| 1IN+ | Channel 1 non-inverting input | Differential input node; matched bias current (<7 nA) enables low-offset transducer interfaces. |
| GND | Analog ground reference | Primary return path for input bias, output load, and internal circuitry; must be low-impedance. |
| VDD+ | Positive supply rail | Operates from 2.7 V to 6 V single supply or ±1.35 V to ±3 V split supply. |
| 2OUT | Channel 2 output | Independent rail-to-rail output; identical AC/DC specs to Channel 1. |
| 2IN− | Channel 2 inverting input | Electrically isolated from Channel 1; enables dual independent signal paths. |
| 2IN+ | Channel 2 non-inverting input | Matched offset and noise performance to Channel 1 for differential pair applications. |

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 |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2462AQDREP's 2 µV/°C; 350 kHz GBW; 17 µA/channel supply current. | Better for DC-critical applications (e.g., weigh scales); unsuitable for >100 kHz signal paths due to lower bandwidth. | Select OPA2333AIDR when long-term DC stability dominates speed/power trade-offs. |
| MCP6022-I/SN | 2.2 MHz GBW; 170 µA/channel; no shutdown pin; 250 µV max offset; rated −40°C to 85°C only. | Limited temperature range excludes under-hood or industrial use; lower drive (25 mA) requires external buffer for heavy loads. | Select MCP6022-I/SN for cost-sensitive consumer applications where extended temperature is not required. |
Compared with OPA2333AIDR and MCP6022-I/SN, TLV2462AQDREP uniquely balances 6.4 MHz bandwidth, 500 µA/channel efficiency, −40°C to 125°C operation, and integrated shutdown-making it optimal for automotive and industrial signal chains demanding speed, precision, and ruggedness.

FAQ
What is the operating temperature range of the TLV2462AQDREP?
The TLV2462AQDREP is specified for continuous operation from −40°C to 125°C, with full electrical performance guaranteed across this range. This extended temperature rating is achieved through JEDEC-qualified reliability testing including biased 85/85, temperature cycling, and HAST-making TLV2462AQDREP suitable for under-hood automotive and industrial control applications where ambient extremes are expected.
Does the TLV2462AQDREP support true rail-to-rail input and output operation?
Yes, the TLV2462AQDREP supports true rail-to-rail input common-mode range (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing (within 100 mV of VDD/GND at 10 mA). This allows full utilization of supply headroom in low-voltage systems like 3.3-V data loggers or 5-V sensor interfaces, maximizing dynamic range without level-shifting circuitry.
How does the shutdown feature of the TLV2462AQDREP function?
The TLV2462AQDREP includes a dedicated SHDN pin (Pin 5 in D-package). Driving SHDN < 0.7 V places both amplifiers into ultralow-power shutdown mode, reducing total supply current to 0.3 µA per channel and forcing outputs into high-impedance state. This enables precise power gating in battery-operated systems-e.g., disabling one channel while the other remains active for wake-up monitoring.
What is the maximum capacitive load the TLV2462AQDREP can drive stably?
The TLV2462AQDREP remains stable with capacitive loads ≤10 pF when directly connected. For loads >10 pF (e.g., ADC input capacitance, cable capacitance), TI recommends inserting a series null resistor (RNULL ≥20 Ω) between the output and load, as documented in Figure 49 of the datasheet. This preserves phase margin (>44°) and prevents oscillation or ringing in precision timing-critical applications.
Is the TLV2462AQDREP pin-compatible with other devices in the TLV246x family?
Yes, the TLV2462AQDREP shares the same 8-pin SOIC (D) package and pinout as TLV2462AMDREP and TLV2462IDR. However, it is not pin-compatible with TLV2463 (14-pin) or TLV2464 (14-pin) variants. All TLV2462-x variants maintain identical pin functions-ensuring drop-in replacement across Q (−40°C to 125°C), M (−55°C to 125°C), and I (−40°C to 85°C) temperature grades when using the D package.
