10-Bit, 12-Bit, Multiplying D/A Converters
Features
Description
• AD7520/AD7530, 10-Bit Resolution; 8-Bit, 9-Bit and The AD7520/AD7530 and AD7521/AD7531 are monolithic,
10-Bit Linearity
high accuracy, low cost 10-bit and 12-bit resolution,
multiplying digital-to-analog converters (DAC). Intersil’
thin-film on CMOS processing gives up to 10-bit accuracy
with TTL/CMOS compatible operation. Digital inputs are fully
protected against static discharge by diodes to ground and
positive supply.
• AD7521/AD7531, 12-Bit Resolution; 8-Bit, 9-Bit and
10-Bit Linearity
• Low Power Dissipation (Max) . . . . . . . . . . . . . . . .20mW
o
• Low Nonlinearity Tempco at 2ppm of FSR/ C
Typical applications include digital/analog interfacing,
multiplication and division, programmable power supplies,
CRT character generation, digitally controlled gain circuits,
integrators and attenuators, etc.
• Current Settling Time to 0.05% of FSR . . . . . . . . 1.0µs
• Supply Voltage Range . . . . . . . . . . . . . . . . ±5V to +15V
• TTL/CMOS Compatible
The AD7530 and AD7531 are identical to the AD7520 and
AD7521, respectively, with the exception of output leakage
current and feedthrough specifications.
• Full Input Static Protection
• /883B Processed Versions Available
