AD7801BRZ

The AD7801BRZ is a single, 8-bit, voltage out DAC that operates from a single +2.7 V to +5.5 V supply. Its on-chip precision output buffer allows the DAC output to swing rail to rail. The AD7801 has a parallel microprocessor and DSP compatible interface with high speed registers and double buffered interface logic. Data is loaded to the input register on the rising edge of CS or WR.

The feature of AD7801BRZ are as follows: (1)Single 8-Bit DAC; (2)20-Pin SOIC/TSSOP Package; (3)+2.7 V to +5.5 V Operation; (4)Internal and External Reference Capability; (5)DAC Power-Down Function; (6)Parallel Interface; (7)On-Chip Output Buffer Rail-to-Rail Operation; (8)Low Power Operation 1.75 mA max @ 3.3 V; (9)Power-Down to 1 mA max @ 258C.

The absolute maximum ratings of the AD7801BRZ are: (1)VDD to GND: 0.3 V to +7 V; (2)reference input voltage to AGND: 0.3 V to VDD + 0.3 V; (3)digital input voltage to DGND: 0.3 V to VDD + 0.3 V; (4)AGND to DGND: 0.3 V to +0.3 V; (5)VOUT to AGND: 0.3 V to VDD + 0.3 V; (6)operating temperature range commercial (B Version): 40°C to +105°C; (7)storage temperature range: 65°C to +150°C; (8)junction temperature: +150°C; (9)SSOP package, power dissipation: 700 mW; (10)JA thermal impedance: 143°C/W; (11)lead temperature, soldering vapor phase: +215°C; (12)infrared: +220°C; (13)SOIC package, power dissipation: 870 mW; (14)JA thermal impedance: 74°C/W; (15)lead temperature, soldering vapor phase: +215°C, Infrared : +220°C.
