ADSP-21991 comparisonADSP-21990Improved memory integration expands the ADSP-2199x mixed-signal DSP product family. The ADSP-21991 integrates a 160 MHz, 16-bit ADSP-219x DSP core with an 8-channel, 14-bit, 20 MSPS ADC with an internal dual sample-and-hold amplifier for simultaneous sampling. Additional mixed-signal circuitry is integrated, including a precision on-chip voltage reference and power-on reset (POR) circuitry. A wide range of control peripherals are available to enable single-chip solutions for embedded control and signal processing applications.
