GENERAL DESCRIPTION
The MP7541B is a pin-compatible replacement which offers superior performance in latch-up and ESD protection versus the comparable 7541 and 7541A. The high ESD protection will reduce failures caused by mishandling. These devices are manufactured using patented advanced thin film resistors on a double metal CMOS process which result in ultra stable thin film and superior long life reliability and stability. The MP7541B incorporates a bit decoding technique yielding lower glitch, higherspeed and excellent accuracy over temperature and time. The MP7541B’s outstanding features are:
Stability: Both Integral Non-Linearity (INL) and Differential-Non-Linearity (DNL) are rated at 0.2 ppm/°C maximum. Monotonicity is guaranteed over the entire temperature range. Gain Temperature Coefficient (TCGE) is 2.0 ppm/°C typical.
Lower Sensitivity to Output Amplifier Offset: Multiplying DACs provide an output current into a virtual ground of the output op amp. Additional linearity error caused by the op amp is reduced by a factor of 3 in the MP7541B versus conventional R-2R DACs.

DESCRIPTION
 The DAC08 series of 8-bit monolithic multiplying Digital-to-Analog Converters provide very high-speed performance coupled with low cost and outstanding applications flexibility.
 Advanced circuit design achieves 70ns settling times with very low glitch and at low power consumption. Monotonic multiplying performance is attained over a wide 20-to-1 reference current range. Matching to within 1 LSB between reference and full-scale currents eliminates the need for full-scale trimming in most applications. Direct interface to all popular logic families with full noise immunity is provided by the high swing, adjustable threshold logic inputs.
 Dual complementary outputs are provided, increasing versatility and enabling differential operation to effectively double the peak-to-peak output swing. True high voltage compliance outputs allow direct output voltage conversion and eliminate output op amps in many
applications.
 All DAC08 series models guarantee full 8-bit monotonicity and linearities as tight as 0.1% over the entire operating temperature range. Device performance is essentially unchanged over the ±4.5V to ±18V power supply range, with 37mW power consumption attainable at ±5V supplies.
The compact size and low power consumption make the DAC08 attractive for portable and military aerospace applications.

FEATURES
• Fast settling output current—70ns
• Full-scale current prematched to ±1 LSB
• Direct interface to TTL, CMOS, ECL, HTL, PMOS
• Relative accuracy to 0.1% maximum over temperature range
• High output compliance -10V to +18V
• True and complemented outputs
• Wide range multiplying capability
• Low FS current drift — ±10ppm/°C
• Wide power supply range—±4.5V to ±18V
• Low power consumption—37mW at ±5V

APPLICATIONS
• 8-bit, 1ms A-to-D converters
• Servo-motor and pen drivers
• Waveform generators
• Audio encoders and attenuators
• Analog meter drivers
• Programmable power supplies
• CRT display drivers
• High-speed modems
• Other applications where low cost, high speed and complete input/output versatility are required
• Programmable gain and attenuation
• Analog-Digital multiplication

GENERAL DESCRIPTION
The AD7628 is a monolithic dual 8-bit digital/analog converter featuring excellent DAC-to-DAC matching. It is available in small 0.3" wide 20-pin DIPs and in 20-terminal surface mount packages. Separate on-chip latches are provided for each DAC to allow easy microprocessor interface. Data is transferred into either of the two DAC data latches via a common 8-bit TTL/CMOS compatible input port. Control input DAC A/DAC B determines which DAC is to be loaded. The AD7628’s load cycle is similar to the write cycle of a random access memory, and the device is bus compatible with most 8-bit microprocessors, including 6502, 6809, 8085, Z80. The device operates from a +12 V to +15 V power supply and is TTL-compatible over this range. Power dissipation is a low 20 mW. Both DACs offer excellent four quadrant multiplication characteristics with a separate reference input and feedback resistor for each DAC.

FEATURES
On-Chip Latches for Both DACs
+12 V to +15 V Operation
DACs Matched to 1%
Four Quadrant Multiplication
TTL/CMOS Compatible from +12 V to +15 V
Latch Free (Protection Schottkys not Required)

APPLICATIONS
Disk Drives
Programmable Filters
X-Y Graphics
Gain/Attenuation
