Frequently Asked Questions
What is the gain-bandwidth product of the OPA1632DGNR?
The OPA1632DGNR has a gain-bandwidth product (GBW) of 180 MHz, making it suitable for wideband fully differential signal processing applications such as high-speed audio ADC drivers and active filters requiring flat frequency response well beyond the audible range.
What are the typical applications for the OPA1632DGNR?
The OPA1632DGNR is primarily used as a fully differential ADC driver in professional audio converters, balanced line drivers in mixing consoles, and precision instrumentation amplifiers. Its ultra-low THD+N of less than 0.00008% and 90 dB CMRR make it ideal for any application demanding exceptional audio fidelity and common-mode noise rejection.
What package does the OPA1632DGNR come in and what is its pin count?
The OPA1632DGNR is housed in an 8-pin MSOP (Micro Small Outline Package) with the DGNR suffix indicating a tape-and-reel packaging option. This compact package is well-suited for space-constrained PCB designs in portable and rack-mount professional audio equipment.
Can the OPA1632DGNR be used as a single-ended to differential converter?
Yes, the OPA1632DGNR can convert a single-ended input signal to a fully differential output. By applying the input signal to one of the two input terminals and connecting the other to a mid-supply reference, the amplifier produces balanced differential outputs with equal amplitude and 180° phase difference, which is a common requirement for driving differential ADC inputs.
