THS4042IDRG4

Instrumentation, Op Amps, Buffer Amps Overview

The THS4042IDRG4 is a dual high-speed voltage-feedback operational amplifier manufactured by Texas Instruments. It features a bandwidth of 165 MHz and a slew rate of 400 V/us. The device operates within a supply voltage range of 9 V to 32 V, drawing 8 mA of quiescent current per channel. Key electrical specifications include an input offset voltage of 2.5 mV, input bias current of 6 uA, and output drive capability of 100 mA per channel. It provides 80 dB voltage gain, 100 dB CMRR, and 75 dB PSRR. The input voltage noise density is 14 nV/sqrt Hz. The component is housed in an SOIC-8 surface-mount package and supports an operating temperature range from -40 C to +85 C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Dual-channel architecture providing two independent high-speed amplifiers in a single package
• Voltage-feedback topology designed for applications requiring fast transient response and wide bandwidth
• High output drive capability supporting loads up to 100 mA per channel
• Low input voltage noise density suitable for precision signal conditioning

Instrumentation, Op Amps, Buffer Amps Applications

• Video buffering and distribution circuits
• ADC driver stages requiring high slew rates
• Test and measurement instrumentation front-ends
• Communication system signal processing

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IDRG4 indicates tape-and-reel packaging distinct from tube variants like ID. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to the sensitive CMOS input stage characteristics inherent to this amplifier family.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when dual-channel performance with 165 MHz bandwidth is required alongside high output current drive. Compare against single-channel alternatives like THS4041 if only one amplifier path is needed. Consider thermal dissipation limits given the 740 mW power dissipation rating in the SOIC-8 package under maximum load conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the THS4042 series of high-speed operational amplifiers from Texas Instruments. It serves as the dual-channel counterpart to the single-channel THS4041. The series is engineered for video and broadband applications where signal integrity and speed are critical. The IDRG4 variant specifically denotes the industrial temperature range version supplied in reel packaging for automated assembly processes.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The THS4042CDG4 is a verified alternative offering identical electrical specifications but limited to a commercial temperature range of 0 C to 70 C instead of the industrial -40 C to +85 C range of the IDRG4 variant.
