Hi , I read the datasheet of the 56F807. The reference voltage of the ADCs are needed. The datasheet said that it would be better to use the 3.0v reference. Anybody know the right chip to set up a 3.0v reference voltage which can drain over 12*2 = 24 mA current (for 2 voltage references)? |

You should read application note AN1947/D: "Understanding the DSP56800
ADC Specifications and Ways to Get the Best Performance in Applications" http://e-www.motorola.com/brdata/PDFDB/docs/AN1947.pdf Leonard -----Original Message----- From: hao yuan [mailto:] Sent: Tuesday, August 13, 2002 12:54 AM To: Subject: [motoroladsp] 56F807: Any Recommedations on The Vref Chips?
