AD5304ARMZ

The AD5304ARMZ is one member of the AD5304 series.The AD5304 is quad 8-, 10- and 12-bit buffered voltage output DACs in a 10-lead microSOIC package that operate from a single 2.5 V to 5.5 V supply consuming 500 A at 3 V. Their on-chip output amplifiers allow rail-torail output swing to be achieved with a slew rate of 0.7 V/s.A 3-wire serial interface is used which operates at clock rates up to 30 MHz and is compatible with standard SPI, QSPI,MICROWIRE and DSP interface standards.

Features of the AD5304ARMZ are:(1)low power operation: 500 A @ 3 V, 600 A @ 5 V; (2)2.5 V to 5.5 V power supply; (3)guaranteed monotonic by design over all codes; (4)power-down to 80 nA @ 3 V, 200 nA @ 5 V; (5)double-buffered input logic; (6)output range: 0-VREF; (7)power-on-reset to zero volts; (8)simultaneous update of outputs (LDAC function); (9)low power, SPI., QSPI., MICROWIRE., and DSP-compatible 3-wire serial interface; (10)on-chip rail-to-rail output buffer amplifiers; (11)temperature range 40 to +105.The low power consumption of these parts in normal operation makes them ideally suited to portable battery-operated equipment.The power consumption is 3 mW at 5 V, 1.5 mW at 3 V, reducing to 1 W in power-down mode.

The absolute maximum ratings of the AD5304ARMZ can be summarized as:(1)VDD to GND:-0.3 V to +7.0 V;(2)digital input voltage to GND:0.3 V to VDD + 0.3 V;(3)VoutA-D to GND:0.3 V to VDD + 0.3 V;(4)storage temperature range:-65 to +150;(5)operating temperature range:-40 to +105;(6)junction temperature range:150.Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.The amplifiers within the DAC have a finite bandwidth. The multiplying bandwidth is a measure of this. A sine wave on the reference (with full-scale code loaded to the DAC) appears on the output. The multiplying bandwidth is the frequency at which the output amplitude falls to 3 dB below the input.
