TS1854IDT

Instrumentation, Op Amps, Buffer Amps Overview

The TS1854IDT is a quad operational amplifier manufactured by STMicroelectronics, housed in a 14-SOIC surface-mount package. It operates within a supply voltage range of 1.8 V to 6 V and features rail-to-rail input and output capabilities. Key electrical specifications include a gain-bandwidth product of 630 kHz, a slew rate of 0.25 V/µs, and an input offset voltage of 1 mV. The device draws a supply current of 162 µA per channel and provides an output current of 48 mA per channel. It supports an extended common-mode voltage range and functions reliably across temperatures from -40°C to +125°C.

• Active filtering circuits

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IDT indicates the 14-SOIC package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements against your manufacturing process standards. Ensure the ordering quantity matches the reel or cut tape specifications provided by the distributor to avoid packaging discrepancies during assembly.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad amplifier with low supply current and rail-to-rail performance is required. The 1 mV input offset voltage makes it suitable for precision applications where higher noise or offset would degrade signal integrity. Consider the 14-SOIC package dimensions for board space constraints compared to TSSOP alternatives.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TS185x family, which includes single (TS1851), dual (TS1852), and quad (TS1854) variants. The family is designed for low-voltage operation starting at 1.8 V, targeting cost-sensitive and power-constrained designs. The TS1854IDT specifically utilizes the industrial temperature grade and SOIC footprint for robust PCB integration.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The TS1854IPT serves as a direct pin-compatible alternative featuring a TSSOP-14 package instead of the SOIC form factor.
