Typical Application
Description
The LTC®2368-24 is a low noise, low power, high speed 24-bit successive approximation register (SAR) ADC with an integrated digital averaging filter. Operating from a 2.5V supply, the LTC2368-24 has a 0V to VREF pseudodifferential unipolar input range with VREF ranging from 2.5V to 5.1V. The LTC2368-24 consumes only 21mW (Typ) and achieves ±4.5ppm INL maximum and no missing codes at 24 bits.
The LTC2368-24 has an easy to use integrated digital averaging filter that can average 1 to 65536 conversion results real-time, dramatically improving dynamic range from 98dB at 1Msps to 140dB at 15.25sps. No separate programming interface or configuration register is required.
The high speed SPI-compatible serial interface supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisychain mode. The LTC2368-24 automatically powers down between conversions, reducing power dissipation at lower sampling rates.
