The MAX154/MAX158 and MX7824/MX7828 are high-speed, multi-channel analog-to-digital converters (ADCs). The MAX154 and MX7824 have four analog input channels, while the MAX158 and MX7828 have eight channels. Conversion time for all devices is 2.5µs. The MAX154/MAX158 also feature a 2.5V on-chip reference, forming a complete high-speed data acquisition system. All four converters include a built-in track/hold, eliminating the need for an external track/hold with many input signals. The analog input range is 0V to +5V, although the ADC operates from a single +5V supply. Microprocessor interfaces are simplified by the ADC’s ability to appear as a memory location or I/O port without the need for external logic. The data outputs use latched, three-state buffer circuitry to allow direct connection to a microprocessor data bus or system input port. The MX7824 and MX7828 are pin compatible with Analog Devices’ AD7824 and AD7828. The MAX154 and MAX158, which feature internal references, are also compatible with these products.

The DS1086 EconOscillator is a programmable clock generator that produces a spread-spectrum (dithered) square-wave output of frequencies from 260kHz to 133MHz. The selectable dithered output reduces radi- ated-emission peaks by dithering the frequency 2% or 4% below the programmed frequency. The DS1086 has a power-down mode and an output-enable control for power-sensitive applications. All the device settings are stored in nonvolatile (NV) EEPROM memory allowing it to operate in stand-alone applications.

The MAX200–MAX209/MAX211/MAX213 transceivers are designed for RS-232 and V.28 communication interfaces where Q12V supplies are not available. On-board charge pumps convert the +5V input to the Q10V needed for RS-232 output levels. The MAX201 and MAX209 operate from +5V and +12V, respectively, and contain a +12V to -12V charge-pump voltage converter. The MAX200–MAX209/MAX211/MAX213 drivers and receivers meet all EIA/TIA-232E and CCITT V.28 specifications at a 20kbps data rate. The drivers maintain the Q5V EIA/TIA-232E output signal levels at data rates in excess of 120kbps when loaded in accordance with the EIA/TIA-232E specification. The 5FW shutdown mode of the MAX200, MAX205, MAX206, and MAX211 conserves energy in battery-powered systems. The MAX213 has an active-low shutdown and an active-high receiver enable control. Two receivers of the MAX213 are active, allowing the ring indicator (RI) to be monitored easily using only 75FW power. The MAX211 and MAX213 are available in a 28-pin, wide small-outline (SO) package and a 28-pin shrink small-outline (SSOP) package, which occupies only 40% of the area.

The DS4026 is a temperature-compensated crystal oscillator (TCXO) that provides ±1ppm frequency stability over the -40°C to +85°C industrial temperature range. The DS4026 is also available in Stratum 3 versions. Each device is factory calibrated over temperature to achieve the ±1ppm frequency stability. Standard frequencies for the device include 10, 12.8, 19.44, 20, 38.88, 40, and 51.84MHz. Contact the factory for custom frequencies. The DS4026 provides excellent phase-noise characteristics. The output is a push-pull CMOS square wave with symmetrical rise and fall times. In addition, the DS4026 is designed to provide a maximum frequency deviation of less than ±4.6ppm over 20 years. The device also provides an I2C interface to allow pushing and pulling of the output frequency by a minimum of ±8ppm (±5ppm for 10MHz) with typical 1ppb resolution. The DS4026 implements a temperature-to-voltage conversion with a nonlinear relationship. The output from the temperature-to-voltage converter is used to drive the voltage-controlled crystal oscillator to compensate for frequency change. The device implements an on-chip temperature sensor lookup table, and a digital-to-analog converter (DAC) to adjust the frequency. An I2C interface used to communicate with the DS4026 performs temperature readings and frequency push-pull.
