THAT 1570/5263 Digital Microphone Preamp Circuit

filler
DESCRIPTION

The THAT1580 and THAT5263 ICs enable digitally controlled microphone preamplifier applications with unprecedented performance. Operating on maximum ±17V supplies, the chipset accepts pro audio input levels (+27.5 dBu max) without an input pad. Gain is adjustable from 0dB to 60dB in 3dB increments. The 5263’s built-in zero-crossing detector and other patent-pending techniques for reducing zipper noise enable very smooth and silent gain changes.

Two general purpose outputs on the 5263 can be connected to a variety of peripheral functions, e.g. input pad, phantom power switches, signal routing switches, LED indicators, etc. Separating the analog mic pre front end (THAT1580) from the digital functions and switched resistor ladder (THAT5263) allows each IC to be optimized for high performance.

Design Note 140   Input and Output Circuits for THAT Preamplifier ICs (244k)

More Analog Secrets Your Mother Never Told You (915k)
At the 127th AES Convention attendees were invited to attend a THAT exhibitor seminar — "More Analog Secrets Your Mother Never Told You". A sequel to our popular first "Analog Secrets" seminar, this new presentation exposes more design secrets including “extreme performance” microphone preamps, protecting audio inputs/outputs during phantom power faults, and maintaining high dynamic range in low cost applications.

Digitally Controlled Microphone Preamplifier Selector
A side by side comparison of the features and specifications of our digitally controlled microphone preamplifier chip sets.

1580/5263 Digitally-Controlled Mic Preamp Demo Board - The THAT 1580/5263 Digitally-Controlled Mic Preamp Demo Board (US$250) allows developers to evaluate the performance of the THAT1580 / THAT5263 chipset. The demo board provides a balanced audio input on a Neutrik "combo" connector with 48V phantom power, and a balanced audio output on XLR and ¼" TRS connectors. The supplied graphical user interface (GUI) controls all functions in the 5263 chip via USB. A prototyping area is available for adding or modifying circuitry. See the 5263 DEMO Datasheet for more information.

1580 and 5263 Surface Mount Adapter Boards - For our integrated circuits which are only available in surface mount packages THAT Corporation offers adapter boards which allow one of these surface-mount ICs to interface to a circuit board via traditional thru-hole mounting. These adapters make it easy for a design engineer to evaluate our surface-mount products on a prototype board without having to employ SMT technology. Adapter boards are available to qualified applicants.
