Product details
Overview
TLV2462CP from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for low-voltage portable systems, delivering 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, and ±80 mA output drive at 500 µA/channel supply current. It features micropower shutdown (0.3 µA/channel), 100 µV input offset voltage, and 11 nV/√Hz input noise voltage - enabling high-fidelity signal buffering in ADC front-ends and sensor interfaces.
For engineers reviewing the TLV2462CP datasheet, TLV2462CP pinout, TLV2462CP application, or TLV2462CP equivalent, this device supports precision analog signal conditioning in battery-powered instrumentation, industrial sensor nodes, and automotive body electronics where rail-to-rail swing, low quiescent current, and wide temperature operation (0°C to 70°C) are critical.
Technical Context
The TLV2462CP implements a CMOS input stage with rail-to-rail common-mode input range extending beyond supply rails and rail-to-rail output swing capable of sourcing/sinking ±80 mA. Its internal architecture enables stable unity-gain operation with 160 pF capacitive load and provides 45° phase margin at 5 V supply.
It integrates independent shutdown control per channel (SHDN pins), placing each amplifier into ultralow-current mode (0.3 µA/channel) while forcing output to high-impedance state. The device operates from 2.7 V to 6 V single supply or ±1.35 V to ±3 V split supply, with specified performance across 0°C to 70°C ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable closed-loop gain up to 10× at 640 kHz without peaking. |
| Slew Rate | 1.6 V/µs - enables clean 100 kHz full-scale sine wave output at 2 VPP with <0.01% THD+N. |
| Supply Current / Channel | 500 µA - allows continuous operation for >1 year on a single CR2032 coin cell in always-on sensor amplifiers. |
| Input Offset Voltage | 100 µV - ensures ≤0.004% gain error in 2.5 V full-scale 12-bit ADC driver applications. |
| Rail-to-Rail Output Swing | Within 100 mV of rails at 10 mA load - maximizes dynamic range in 3.3 V systems driving SAR ADC references. |
| Shutdown Current / Channel | 0.3 µA - reduces system standby power by >99.9% versus active mode, critical for duty-cycled IoT nodes. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - preserves SNR in low-level thermocouple or bridge sensor amplification paths. |
Pinout & Package
TLV2462CP is housed in an 8-pin plastic DIP (P) package with 0.3-inch body width and through-hole mounting. Pin spacing is 0.1 inch, compatible with standard PCB layouts and socketing.
| Pin | Circuit Role | Design Meaning |
|---|---|---|

| 4 | GND | Analog ground reference for both channels and shutdown logic; must be low-impedance. |
| 5 | SHDN A | Active-high shutdown control for Channel A; <0.7 V disables, >2 V enables amplifier. |
| 6 | VDD+ | Positive supply rail; operates from 2.7 V to 6 V; decoupling capacitor required at pin. |
| 7 | OUT B | Inverting amplifier output terminal for Channel B; electrically identical to Pin 1. |
| 8 | IN− B | Inverting input of Channel B; independent of Channel A; shares same GND and VDD. |

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 |
|---|---|---|---|
| TLV2462CD | Same electrical specs but in SOIC-8 package; thermal resistance θJA = 176°C/W vs 104°C/W for P package. | Better suited for surface-mount automated assembly and higher-density PCBs; less suitable for prototyping or through-hole test fixtures. | Select TLV2462CD for volume production with reflow soldering; retain TLV2462CP for breadboarding, manual assembly, or legacy through-hole designs. |
| OPA2340UA | Higher GBW (10 MHz), lower noise (8 nV/√Hz), but no shutdown function and higher supply current (800 µA/channel). | Preferred for high-speed, low-noise applications where power budget allows; unsuitable for duty-cycled or ultra-low-power systems. | Choose OPA2340UA when bandwidth or noise dominates design priorities; TLV2462CP remains optimal when shutdown capability and sub-1 mA total supply current are mandatory. |
Compared with TLV2462CD and OPA2340UA, the TLV2462CP uniquely balances through-hole accessibility, micropower shutdown, and rail-to-rail performance in a cost-effective DIP package - making it the preferred choice for development, low-volume instrumentation, and applications requiring field-serviceable components.

FAQ
What is the operating temperature range for TLV2462CP?
The TLV2462CP is rated for operation from 0°C to 70°C ambient temperature, as indicated by its 'C' suffix. This commercial-grade specification makes it suitable for consumer electronics, portable instrumentation, and non-automotive industrial equipment where extended temperature ranges are not required. Full electrical performance is guaranteed across this range, including input offset voltage, gain bandwidth, and output drive capability.
Does TLV2462CP support true rail-to-rail input and output?
Yes, TLV2462CP supports true rail-to-rail input common-mode voltage range (GND to VDD) and rail-to-rail output swing (within 100 mV of rails at 10 mA). This is confirmed in the datasheet's "Rail-to-Rail Output Swing" headline and electrical characteristics tables, enabling full dynamic range utilization in single-supply 3.3 V or 5 V systems without external level-shifting circuitry.
How does the shutdown feature work on TLV2462CP?
The TLV2462CP includes independent active-high shutdown pins (Pin 5 for Channel A, Pin 8 is NC; note: TLV2462CP uses Pin 5 for SHDN A and has no SHDN B - only TLV2463/2465 provide dual shutdown). When SHDN A is pulled below 0.7 V, Channel A enters ultralow-current mode (0.3 µA/channel) and its output goes high-impedance. Channel B remains active unless externally disabled via external circuitry.
What is the maximum capacitive load TLV2462CP can drive stably?
TLV2462CP maintains stability with up to 160 pF capacitive load at unity gain, as verified in the "Operating Characteristics" table and Figure 36 (Phase Margin vs Load Capacitance). For loads exceeding 160 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to preserve phase margin above 30° and prevent oscillation in ADC buffer or cable-driving configurations.
Can TLV2462CP operate from a single 3.3 V supply?
Yes, TLV2462CP is fully specified for single-supply operation from 2.7 V to 6 V, including 3.3 V. At 3.3 V, it delivers 6.4 MHz GBW, 1.6 V/µs slew rate, rail-to-rail input/output, and 500 µA/channel supply current - all confirmed in the "Electrical Characteristics at VDD = 3 V" section. This makes TLV2462CP ideal for modern 3.3 V microcontroller-based sensor nodes and portable equipment.
