HT8972 next-generation echo chip, built-in 40KB SRAM

The HT8972 contains four operational amplifiers and a built-in AD / DC converter, which greatly reduces external use parts and costs and increases product competitiveness. The HT8972 is packaged in a 16DIP / SOP and has fully compatible pins and the same application circuit as the HT8970. Old customers can quickly upgrade existing products, and new customers can easily design and import into production. With excellent prices and perfect sound quality, the HT8972 is the best echo IC for karaoke, audio equipment, electronic musical instruments, toys and other applications.

HOLTEK Semiconductor has accumulated years of technical experience in the echo IC market and launched a new generation of echo IC: HT8972. The HT8972 has a built-in 40KB SRAM (the previous generation echo IC HT8970 has a built-in 20KB SRAM), which makes the echo effect more delicate and the signal-to-noise ratio higher.

The HT8972 is an echo / surround effect processor. It is designed for various audio systems including karaoke, television, sound equipments, etc. The chip consists of
a built-in pre-amplifier, VCO or Voltage Control OSC, 40Kb SRAM, A / D and D / A converters as well as delay TIme control logic.

Yuhai company develop and produce of various tube/cylinder sizes, bearing variety of electrode and metallisation configurations. The tubes is fabricated from various published and additional custom in-house Piezoelectric Material formulations for applications such as high power, sensitivity, stability needs.
