Nonvolatile DACs come in duals and quads
New from Maxim Integrated Products are the MAX5108/MAX5109 (dual) and MAX5115/MAX5116 (quad) nonvolatile, rail-to-rail, buffered, 8bit D/A convertors (DACs).
New from Maxim Integrated Products are the MAX5108/MAX5109 (dual) and MAX5115/MAX5116 (quad) nonvolatile, rail-to-rail, buffered, 8bit D/A convertors (DACs) These nonvolatile devices are the only DACs available in the industry with a high-speed two-wire I2C interface that accepts datarates up to 400Ksample/s

Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
Low-power serial ADC runs up to 200Ksample/s
New from Maxim Integrated Products, the MAX1162 serial-interface 16bit A/D convertor connects directly to SPI, QSPI and Microwire devices without additional interface logic.
The devices are also highly accurate and guaranteed monotonic over the full operating temperature range.
These low-cost, 8bit DACs are ideal for applications such as digital gain and offset adjustment, programmable attenuators, portable instruments and power-amp bias control.
The MAX5108/MAX5109 and MAX5115/MAX5116 feature a single +2.7 to +5.5V supply range and low 200uA per DAC supply current during write operations.
In comparison, the closest nonvolatile DAC competitor consumes 3mA.
A software-selectable shutdown feature reduces the supply current to 20uA (maximum), compared with the closest competition's 1mA of shutdown current.
The MAX5108/MAX5109 and MAX5115/MAX5116 power-up with the last command stored in the nonvolatile memory (prior to power-down) and transferred to the DAC registers, which set the DAC outputs to a predefined value.
A mute function independently drives each DAC output to its respective low-side reference voltage.
Addressing options allow multiple devices to be connected to the same I2C bus.
The MAX5108/MAX5109 are available in 6 x 5mm 16-pin QSOP packages, and the MAX5115/MAX5116 are available in 6 x 8.5mm 20-pin QSOP packages.
Prices for the MAX5108/MAX5109 and the MAX5115/MAX5116 start at $3.37 and $5.97, respectively (1000-up, FOB USA).
