MAXREFDES32#: 2-Channel Analog Input/Analog Output with Flyback DC-DC (MAXREFDES32)
Advanced manufacturing, custom production and cost pressures continue to drive factories to higher speed performance and increased flexibility. To meet the requirements of a ‘no compromises’ factory environment, the MAXREFDES32# subsystem reference design provides two high-speed, high-accuracy, 400ksps, 16-bit analog input channels and output channels. All input and output channels support ±10V and ±20mA signals plus 20% margin, providing flexibility for low- and high-speed systems using either voltage or current signals.
The MAXREFDES32# design utilizes four dual fast-settling high-voltage op amps (MAX9633); two 16-bit 500ksps ADCs (MAX11166); two low-noise, fast-settling precision 16-bit DACs (MAX5316); two ultra-high precision 4.096V voltage references (MAX6126); seven high-speed digital isolators (MAX14850); a peak-current-mode converter for flyback/boost supplies (MAX17498B); and regulated +18V, -18V, +5V, and -1.25V power rails (MAX8719, MAX8881). By using high-accuracy and high-speed components, this subsystem performs well in both process control applications, such as sensor inputs, and control applications, such as servo drives, resolvers, and encoders.
