TLV2785IN

Instrumentation, Op Amps, Buffer Amps Overview

The TLV2785IN is a quad operational amplifier manufactured by Texas Instruments, housed in a 16-pin PDIP package. It operates within a supply voltage range of 1.8 V to 3.6 V and supports dual supplies from 0.9 V to 1.8 V per rail. The device features an 8 MHz gain-bandwidth product and a slew rate of 5 V/µs. Key electrical specifications include a maximum input offset voltage of 3 mV, input bias current of 15 pA, and quiescent current of 650 µA for all four channels. Each channel provides an output current capability of 23 mA with rail-to-rail input and output swing. The common-mode rejection ratio is 100 dB, and the input voltage noise density is 18 nV/√Hz. It functions reliably across an industrial temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IN' corresponds to the PDIP-14 through-hole package variant when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation, as environmental declarations may vary by production batch. Ensure the supplier provides traceable datasheets matching the TLV2785 family specifications. Cross-reference the ordering part number against the latest Texas Instruments product selection guide to confirm availability and manufacturing status before finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad configuration is required alongside rail-to-rail performance and low voltage compatibility. The 8 MHz bandwidth suits moderate-speed applications where power efficiency is critical. Compare against single or dual-channel variants if fewer amplifiers are needed to reduce board space. Consider the PDIP package constraints for automated assembly versus surface-mount alternatives like the ID or IDBVT versions if PCB layout favors SMD components.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the TLV278x series of low-voltage, high-speed operational amplifiers from Texas Instruments. The series includes single (TLV2781), dual (TLV2782), and quad (TLV2785) channel options. All variants share similar electrical characteristics, including rail-to-rail I/O and low quiescent current, designed for battery-operated systems. The TLV2785 specifically integrates four amplifiers, offering a compact solution for multi-channel signal processing tasks without increasing component count significantly.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Publicly confirmed substitute part numbers include TLV2785ID and TLV2785AID. These variants offer identical electrical specifications but utilize different packaging formats such as SOIC or TSSOP instead of the PDIP housing.
