THS3115CDR

Instrumentation, Op Amps, Buffer Amps Overview

The THS3115CDR is a dual low-noise, high-speed current-feedback amplifier manufactured by Texas Instruments. It operates within a supply voltage range of ±5 V to ±15 V (single supply 10 V to 30 V). Key electrical parameters include a small-signal bandwidth of 110 MHz at unity gain and a slew rate of 1550 V/µs. The device features a shutdown mode with a quiescent current of 300 µA per channel. It is housed in an SOIC-8 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'CDR' corresponds to the commercial temperature range (-40°C to +85°C) and SOIC-8 tape-and-reel packaging configuration. Confirm that the datasheet revision matches the required design specifications. Ensure ESD handling precautions are observed during assembly due to the sensitivity of precision integrated circuits.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high slew rates and wide bandwidth are critical alongside low noise performance. The THS3115 is distinct from the THS3112 due to its integrated shutdown pin, offering power management benefits. Consider the requirement for a feedback resistor for stability optimization. Evaluate thermal dissipation requirements based on the specific PCB layout and ambient operating conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the THS311x family of current-feedback operational amplifiers designed for high-speed analog signal processing. The THS3115 variant specifically includes a shutdown feature not present in the THS3112. Both devices share similar dynamic performance metrics but differ in power management capabilities and package availability options.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

THS3112CDR serves as a functional substitute if the shutdown pin is not utilized in the circuit design. Verify pin compatibility and ensure the absence of the shutdown control requirement before substitution.
