Philips Semiconductors Linear Products
8-bit multiplying D/A converter
Product specification
MC1508-8/1408-8
DESCRIPTION
The MC1508/MC1408 series of 8-bit monolithic digital-to-analog
converters provide high-speed performance with low cost. They are
designed for use where the output current is a linear product of an
8-bit digital word and an analog reference voltage
FEATURES
• Fast settling time — 70ns (typ)
• Relative accuracy ±0.19% (max error)
• Non-inverting digital inputs are TTL and CMOS compatible
• High-speed multiplying rate 4.0mA/µs (input slew)
• Output voltage swing +0.5V to –5.0V
• Standard supply voltages +5.0V and –5.0V to –15V
• Military qualifications pending
APPLICATIONS
• Tracking A-to-D converters
• 2 1/2-digit panel meters and DVMs
• Waveform synthesis
• Sample-and-Hold
• Peak detector
• Programmable gain and attenuation
• CRT character generation
• Audio digitizing and decoding
• Programmable power supplies
• Analog-digital multiplication
• Digital-digital multiplication
• Analog-digital division
• Digital addition and subtraction
• Speech compression and expansion
• Stepping motor drive modems
• Servo motor and pen drivers
