High-channel-count DACs suit optical
conversion
A new family of high-density DACs features the industry's first 40-channel, 14bit resolution, voltage-output DAC operating from a single 5V power supply.
Ideal for optical networking systems, Analog Devices' new family of high-density DACs features the industry's first 40-channel, 14bit resolution, voltage-output DAC operating from a single 5V power supply - the AD5380 A 32-channel version is available as well - the AD5382

A/D convertor measures smaller signals faster
Sigma-delta ADC achieves greater than true 16bit noise-free resolution up to 2.4kHz across all input voltages from 40mV to 5V.
SAR convertor claims record speed and accuracy
A/D convertor achieves a new level of 16bit data capture performance, with best-in-class 15bit ENOB and 10Msample/s throughput.
The DACs' high-channel count facilitates control of large numbers of wavelengths in small spaces, which is of great benefit to optical DWDM systems.
Both devices contain on-chip, low-drift references, eliminating the need for an external reference IC, reducing cost and board space.
The parts also include user-programmable offset and gain for digital range adjustment and system calibration.
These DACs offer high accuracy and increased functionality, including a boost mode that allows the parts to achieve faster settling times and a load DAC function that allows simultaneous update of all DAC outputs.
The high-performance AD5380 and AD5382 provide rail-to-rail outputs that operate up to a maximum of 5V.
They contain a parallel interface and both SPI1 and I2C serial interfaces.
The devices are pin-compatible with the rest of Analog Devices' AD538x family, which includes the AD5381 40-channel, 12bit DAC and the AD5383, 32-channel, 12bit DAC.
Analog Devices also offers a 40-channel, 14bit DAC, the AD5379, which is bipolar and operates from +5, +12 and -12V supplies.
The AD5380 and AD5382 are ideal for optical networking applications, such as variable optical attenuator (VOA) control, MEMS mirror and optical switch control, and erbium doped fibre amplifier (EDFA) pump laser control.
They are also well suited for automatic test equipment (ATE) level-setting applications.
The AD5380 and AD5382 are sampling now in 100-lead LQFPs and are priced per unit at $49.50 and $42.50, respectively, in 1000-piece quantities.
