05% Total Unadjusted Error (TUE) Max User programmable Offset and Gain On Chip Diagnostics On-Chip Reference (±5 ppm/°C Max) −40°C to +105°C Temperature Range AD5757/AD5737 GENERAL DESCRIPTION The AD5757/AD5737 is a quad, current output DAC, which operates with a power supply of up to +33v.
On chip dynamic power control minimizes package power dissipation in current mode.
This is achieved by regulating the voltage on the output driver from between 7V-30V.
Each channel has a corresponding CHART pin so that HART signals can be coupled onto the AD5757/AD5737’s current output.
The part uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and that is compatible with standard SPI®, QS...
