AD5735ACPZ

AD5735 is a quad-channel voltage and current output DAC with dynamic power control that operates with a power supply range from -26.4V to +33V. On-chip dynamic power control minimizes package power dissipation in current mode. This reduced power dissipation is achieved by regulating the voltage on the output driver from 7.4V to 29.5V using a dc-to-dc boost converter optimized for minimum on-chip power dissipation. This uses a versatile 3-wire serial interface that operates at clock rates of up to 30MHz and is compatible with standard SPI, QSPI™, MICROWIRE®, DSP, and microcontroller interface standards. The serial interface also features optional CRC-8 packet error checking, as well as a watchdog timer that monitors activity on the interface. Application includes process control, actuator control, PLCs.

• Dynamic power control for thermal management
• Current and voltage output pins connectable to a single terminal
• User-programmable offset and gain, on-chip diagnostics
• Resolution is 12bits (min, AVDD = VBOOST-x = 15V, DVDD = 2.7V to 5.5V)
• Total unadjusted error (TUE) is ±0.012% FSR (typ, 0V to 5V, 0V to 10V, ±5V, ±10V ranges)
• Relative accuracy (INL) is ±0.006% FSR (typ, AVDD = VBOOST-x = 15V, DVDD = 2.7V to 5.5V)
• Differential nonlinearity (DNL) range from -1 to +1LSB (guaranteed monotonic, AVDD = VBOOST-x = 15V)
• Short-circuit current is 16/8mA (typ, Programmable by user, defaults to 16mA typical)
• DC PSRR is 50µV/V (typ, AVDD = VBOOST-x = 15V, DVDD = 2.7V to 5.5V)
• 64-lead LFCSP-VQ package, operating temperature range from -40°C to +105°C
