Key Features

  • Ultra-low THD+N of <0.00008% for high-fidelity audio signal integrity
  • 180 MHz gain-bandwidth product enables wideband fully differential signal processing
  • 45 V/µs slew rate supports fast transient response in demanding audio applications
  • Fully differential architecture rejects common-mode noise for balanced line driving
  • Low input bias current of 0.14 µA (typ) minimizes offset errors in precision circuits
  • Available in space-saving 8-pin MSOP package (DGNR) for compact PCB designs

Applications

The OPA1632DGNR is widely used as an ADC driver in high-performance audio DAC/ADC systems, where its fully differential topology and ultra-low distortion ensure clean signal conversion. It is also deployed in professional audio mixing consoles and preamplifiers as a balanced line driver, taking advantage of its high common-mode rejection ratio of up to 90 dB. Additionally, the device suits instrumentation and medical audio signal conditioning applications that demand precision, low noise, and wide bandwidth.

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.
