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.
The MAX5437/MAX5439 include a general-purpose, on-chip, high-voltage, uncommitted operational amplifier, which provides additional reductions in board space and cost.
These new digital pots use dual operating voltages of +/-5V to +/-15V, or single operating voltages, such as 0 to +10, 0 to +15, or 0 to +30V.
The MAX5436-MAX5439 are excellent for liquid crystal display (LCD) contrast adjustment or high-voltage trimming applications.
Other features include low 35ppm/degC end-to-end and 5ppm/degC ratiometric resistor temperature coefficients, a three-wire SPI/QSPI/Microwire-compatible serial interface, power-on reset to midscale, and an amplifier shutdown mode.
The MAX5436/MAX5437 are available in 50kohm resistances and the MAX5438/MAX5439 in 100kohm resistances.
Prices for the MAX5436/MAX5438 without the on-chip amplifier in a microMAX package are $0.92 (100,000-up, FOB USA).
Prices for the MAX5437/MAX5439 with the on-chip amplifier in a TSSOP package start at $1.24 (100,000-up, FOB USA).
