Overview: Analog Reinvented ES9826
32-bit High performance 2 Channel ADC w/PGA Product Datasheet The SABRE® ES9826 is a 32-bit analog-to-digital (A/D) converter targeted for professional audio applications such as recording systems, professional microphones, video conferencing, digital turntables, IP network camera systems, smart speakers, and other consumer applications.
The ES9826 has 2 integrated ADCs which use ESS’ patented Hyperstream® IV ADC architecture, and a front-end PGA which delivers unprecedented audio sound quality and specifications, including a DNR of +123dB and a THD+N of -105dB in 2 channel mode with a 2.5kΩ input impedance.
The ES9826 introduces a new optional Auto Ranging Enhancement (ARE) function that broadens the dynamic range of the source material while maintaining audio integrity.
The SABRE ADC supports S/PDIF, I2S/LJ master/slave, and TDM digital output formats. The ES9826 can be controlled by software (I2C/SPI) or hardware mode (HW) to reduce or eliminate programming with external source.
A programmable microphone bias regulator is integrated for reduction of BOM requirements when using analog microphones.
Built-in digital filters with pre-programmed filter coefficients that allow for sound and latency preferences. The ES9826 has an Ultra-Low Noise Floor Bandwidth of 200kHz. This bandwidth is up to 10 times wider than the competition, enabling higher resolution at higher sample rates.
