The MX7548 is a 12-bit CMOS, current output, multiplying digital-to-analog converter (DAC) with a versatile interface for microprocessors using 8-bit busses. The MX7548 accepts data into its input-registers in two bytes in either left- or right-justified format, lease significant byte or most significant byte first. Standard active-low WR and active-low CSLSB or active-low SCMSB inputs control the data load operation. A separate active-low LDAC input controls transfer of data from the input register to the DAC register allowing for simultaneous update of all DACs in multi-DAC systems. A data override input forces the DAC output to full-scale or zero-code without altering the contents of the input registers. This permits the user to perform DAC calibration conveniently without having to load calibration data into the DAC. The MX7548 works with a single +5V, +12V or +15V power supply, and the electrical characteristics are specified at all of these supply voltages. All digital inputs are TTL and +5V-CMOS compatible with any of these supply voltages. Maxim MX7548 uses low tempco thin-film resistors which are laser trimmed to ±¼ LSB linearity and better than ±1 LSB gain accuracy. The digital inputs are designed with improved ESD protection and can typically withstand over 5,000V of ESD voltages. The MX7548 is supplied in 20-lead narrow DIP, PLCC, and Small Outline packages.ApplicationsµP-Controlled SystemsAutomatic Test EquipmentDigitally Controlled FiltersMotion Control SystemsProcess ControlProgrammable Gain AmplifiersProgrammable Power Supplies

The OP-27/OP-37 series of operational amplifiers combine outstanding noise performance with excellent precision and high speed specifications. The wideband noise is only 3nV/√Hz, and with the 1/f noise corner at 2.7Hz, low noise is maintained for all low frequency instrumentation applications. Precision DC specifications match or exceed the best available op amps: offset voltage is 10µV, drift with temperature and time are 0.2µV/°C and 0.2uv/month, respactively; common mode rejection is 126dB, voltage gain is two million. The unity gain compensated OP-27 is an order of magnatude faster than other precision op amps. The decompensated OP-37 is even faster at a gain-bandwidth product of 63MHz an 17V/usec slew rate. These characteristics plus our advanced process and test techniques make the OP-27/OP-37 an excellent choice for performance and reliability in all low noise, precision amplifier applications. In addition, ADI's OP-37 is completely latch-up free in high gain, large capacitive feedback configurations.
