The LTC2440CGNPBF is a 24-bit A/D converter from Analog Devices. It has a wide input voltage range of 4.5V to 40V and a low noise, bandwidth of 500kHz. It features selectable FSR, rail-to-rail input and output, temperature drift of only 0.7ppm/°C, and ±0.05mV INL accuracy. It is composed of a low noise charge redistribution SAR ADC, a low drift, low power low noise reference, and 12-bit LED driver with shutdown control. It is suitable for high resolution industrial and instrumentation applications such as automation, metering, and medical equipment. The device is available in a small leadless MSOP-10 package.
