ADC has integrated digital filter
Astute Electronics, the leading supplier of electronic components and value added services, has introduced the Linear Technology LTC2380-24 24bit low-power SAR analogue-to-digital converter (ADC) with integrated digital filter. The LTC2380-24 is a low noise, low power, high-speed 24bit successive approximation register (SAR) 1.5 and 2.0Msps ADC with an integrated digital averaging filter. Operating from a 2.5V supply, it has a ±VREF fully differential input range with VREF from 2.5 to 5.1V. Power consumption is only 28mW and it achieves ±3.5ppm INL maximum and no missing codes at 24bit.
Comments Ian Fantham, Sales Director, Astute Electronics: “The LTC2440 is for applications such as seismology, energy exploration, medical imaging, high-speed data acquisition, industrial process control and automatic test equipment.”
The device has an easy to use integrated digital averaging filter that can average 1 to 65536 conversion results in real time, dramatically improving dynamic range from 101dB at 1.5Msps to 145dB at 30.5sps. No separate programming interface or configuration register is required. A high-speed SPI-compatible serial interface supports 1.8, 2.5, 3.3 and 5V logic while also featuring a daisy-chain mode. The LTC2380-24 automatically powers down between conversions, reducing power dissipation at lower sampling rates. Operation is guaranteed at up to +85°C. It comes in 16-lead MSOP and 4 by 3mm DFN packages.
