Typical Application
Description
The LTC®2380-24 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 LTC2380-24 has a ±VREF fully differential input range with VREF ranging from 2.5V to 5.1V. The LTC2380- 24 consumes only 28mW and achieves ±3.5ppm INL maximum and no missing codes at 24 bits.
The LTC2380-24 has an easy to use integrated digital averaging filter that can average 1 to 65536 conversion results real-time, dramatically improving dynamic range from 101dB at 1.5Msps to 145dB at 30.5sps. 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 LTC2380-24 automatically powers down between conversions, reducing power dissipation at lower sampling rates.
