Texas Instruments TLV2624IPWR

Overview

TLV2624IPWR from Texas Instruments is a quad-channel, rail-to-rail output CMOS operational amplifier optimized for single-supply operation from 2.7 V to 5.5 V. It delivers 11 MHz gain-bandwidth, 10 V/µs slew rate, 27 nV/√Hz input voltage noise, 800 µA per channel supply current, and ultralow 4 µA/channel shutdown current - enabling high-speed signal conditioning in battery-powered data acquisition and sensor interface systems.

For engineers reviewing the TLV2624IPWR datasheet, TLV2624IPWR pinout, TLV2624IPWR application, or TLV2624IPWR equivalent, key selection criteria include its industrial-grade temperature range (–40°C to 125°C), TSSOP-14 package with integrated 1/2SHDN and 3/4SHDN control pins, rail-to-rail output swing, and positive-rail-inclusive input common-mode range - critical for precision analog front-ends interfacing with ADCs and microcontrollers.

Technical Context

The TLV2624IPWR implements a CMOS input stage with rail-to-rail output architecture, supporting full-swing operation into 2 kΩ loads while maintaining phase margin ≥63° at 10 pF capacitive load. Its input common-mode range extends from 1 V to VDD + 0.2 V, enabling direct connection to positive-referenced sensors and DAC outputs without level-shifting.

Each of the four amplifiers features independent shutdown control via dedicated 1/2SHDN (Pin 8) and 3/4SHDN (Pin 9) inputs, allowing selective channel disabling to reduce system power. The device operates across the full industrial temperature range with guaranteed performance at both 2.7 V and 5 V supplies, making it suitable for Li-ion powered instrumentation and mixed-voltage embedded systems.

FAQ

What is the maximum capacitive load the TLV2624IPWR can drive while maintaining stability?

The TLV2624IPWR is characterized for stable operation with up to 10 pF capacitive load at unity gain when RL = 2 kΩ, delivering ≥63° phase margin. Driving larger loads (e.g., ADC input capacitance >10 pF) requires isolation via series resistor (≥100 Ω) or careful compensation per Figure 16 in the datasheet. Layout parasitics must also be minimized to avoid unintended peaking.

Does the TLV2624IPWR support true single-supply operation with input signals near ground?

No - the TLV2624IPWR's input common-mode range starts at 1 V (not GND), so it cannot directly amplify signals below 1 V when operating from a single supply. For ground-referenced inputs, use a level-shifting circuit or select an op-amp with rail-to-rail input (e.g., TLV9064). The TLV2624IPWR excels when inputs are referenced to mid-supply or above.

How does the shutdown feature of the TLV2624IPWR affect output state?

When either 1/2SHDN (Pin 8) or 3/4SHDN (Pin 9) is pulled low (<0.4 V), the corresponding amplifier pair enters high-impedance output state - neither sourcing nor sinking current. Outputs do not short to GND or float unpredictably; they remain at their last valid voltage until re-enabled, preventing downstream loading during sleep modes.

Can the TLV2624IPWR be used with a 1.8 V supply?

No - the TLV2624IPWR has a minimum recommended supply voltage of 2.7 V. Operation below this risks undefined behavior, reduced output swing, increased input offset, and potential failure to meet AC specifications. For 1.8 V systems, consider TI's TLV2784 or OPA316 families, which are explicitly characterized down to 1.8 V.

What is the typical input bias current of the TLV2624IPWR, and how does it impact high-impedance sensor interfaces?

The TLV2624IPWR exhibits typical input bias current of 2 pA at 25°C (max 200 pA over temperature), due to its CMOS input stage. This enables direct connection to high-impedance sources like photodiodes or pH electrodes without significant voltage error - e.g., a 100 MΩ source contributes only 0.2 mV offset, preserving accuracy in precision measurement circuits using TLV2624IPWR.
