Maxim MAXREFDES32 reference design

Maxim’s MAXREFDES32 reference design provides two high-speed, high-accuracy, 400 kSps, 16-bit analog input channels and output channels to meet the factory environments of today’s advanced manufacturing.

The design utilises four dual fast-settling high-voltage op amps (MAX9633); two 16-bit 500 kSps ADCs (MAX11166); two low-noise, fast-settling precision 16-bit DACs (MAX5316); two ultrahigh-precision 4.096 V voltage references (MAX6126); seven high-speed digital isolators (MAX14850); a peak-current-mode converter for flyback/boost supplies (MAX17498B); and regulated +18, -18, +5 and -1.25 V power rails (MAX8719, MAX8881).

By using high-accuracy and high-speed components, the subsystem performs well in both process control applications, such as sensor inputs, and control applications, such as servo drives, resolvers and encoders.
