TLV2704IN

Overview

The TLV2704IN is a quad special-purpose amplifier from Texas Instruments, integrating two operational amplifiers and two push-pull comparators within a single package. It operates on a supply voltage range of 2.5 V to 16 V with a typical quiescent current of 1.4 µA per channel. The device features rail-to-rail input and output capabilities, ensuring maximum dynamic range. Key electrical specifications include a gain-bandwidth product of 5.5 kHz, a slew rate of 0.0025 V/µs, and an input bias current of 250 pA. It provides a common-mode rejection ratio of 88 dB and can source or sink up to 10 mA per channel. The component is housed in a 14-pin SOIC package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Integrates dual operational amplifiers and dual push-pull comparators for mixed-signal applications
• Rail-to-rail input and output stages maximize signal swing across the supply range
• Ultra-low power consumption suitable for battery-operated systems
• High input impedance with low input bias current minimizes loading effects

Applications

• Battery-powered sensor interfaces requiring mixed analog and digital logic functions
• Low-frequency signal conditioning circuits
• Threshold detection and monitoring systems
• Portable instrumentation devices

Procurement Notes

Verify the suffix 'IN' corresponds to the PDIP-14 through-hole package variant rather than the 'ID' SOIC surface-mount version. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the specific lot code matches project requirements for automotive or industrial qualification if applicable. Cross-reference the datasheet revision date to ensure parameter consistency with design simulations.

Selection Notes

Select this component when a single package must handle both linear amplification and comparator switching tasks. The low bandwidth and slew rate make it unsuitable for high-speed signals but ideal for precision DC or low-frequency AC applications. Compare against the OPA2704 series if higher speed is required, noting the significant difference in gain-bandwidth product. Verify that the 10 mA output drive capability meets load requirements without excessive heat dissipation.

Part Context

This part belongs to the TLV2704 family of low-power, rail-to-rail amplifiers. It shares architectural similarities with the TLV2774 and TLV2764 but offers distinct functionality by combining op-amps and comparators. Unlike the TLC274 which focuses on precision, the TLV2704 prioritizes power efficiency and mixed-function integration. It serves as a cost-effective solution for reducing component count in compact designs.
