THS4151CDGN

Instrumentation, Op Amps, Buffer Amps Overview

The THS4151CDGN is a fully differential input/output high slew rate amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 5 V single-supply to ±15 V dual-supply, with an absolute maximum rating of ±16.5 V. The device features a small-signal bandwidth of 150 MHz at unity gain and a typical slew rate of 650 V/µs. Key electrical characteristics include an input-referred noise of 7.6 nV/√Hz, a common-mode rejection ratio (CMRR) of 83 dB, and a quiescent current of 17.5 mA at ±15 V. It is housed in an 8-lead MSOP PowerPAD package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Fully differential signal path from input to output for improved total harmonic distortion and common-mode noise rejection
• High-speed performance with 150 MHz bandwidth and 650 V/µs slew rate
• Wide power-supply range supporting single-supply operation down to 5 V
• Integrated output common-mode control terminal for precise DC level setting

Instrumentation, Op Amps, Buffer Amps Applications

• Differential ADC driver
• Single-ended to differential conversion
• Differential transmitter and receiver
• Differential antialiasing filter

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'CDGN' corresponds to the commercial temperature range (0°C to 70°C) and the MSOP PowerPAD package type. Confirm that the component matches the Texas Instruments datasheet SLOS321G specifications. Ensure the supplier provides traceability documentation consistent with production data standards.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fully differential architecture is required to reject common-mode noise and reduce even-order harmonics. It is suitable for applications demanding high slew rates and wide bandwidth. Consider the thermal requirements of the PowerPAD package for heat dissipation. Verify that the input common-mode voltage range aligns with the system's signal levels.

Instrumentation, Op Amps, Buffer Amps Part Context

The THS4151 is part of the THS415x family of high-speed differential I/O amplifiers fabricated using BiComI complementary bipolar process. It shares pinouts and functionality with the THS4150, which includes a shutdown mode. The CDGN variant specifically denotes the commercial temperature grade and surface-mount packaging.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The THS4150CDGN is a direct functional substitute with the addition of a shutdown pin. Other family members like the THS4141 offer different speed and noise profiles but require circuit adjustments.
