The LTC2381-16 is a low noise, low power, high speed 16-bit successive approximation register (SAR) ADC. Operating from a 2.5V supply, the LTC2381-16 has a ±2.5V fully differential input range. The LTC2381-16 consumes only 3.25mW and achieves ±2LSB INL max, no missing codes at 16-bits and 92dB SNR.
The LTC2381-16 has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisychain mode. The fast 250ksps throughput with no cycle latency makes the LTC2381-16 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2381-16 automatically powers down between conversions, leading to reduced power dissipation that scales with the sampling rate.
The LTC2381-16 features a proprietary sampling architecture that enables the ADC to begin acquiring the next sample during the current conversion. The resulting extended acquisition time of 3.25μs allows the use of extremely low power ADC drivers.
