Product Details
The LTC2380-16 is a low noise, low power, high speed 16-bit successive approximation register (SAR) ADC. Operating from a 2.5V supply, the LTC2380-16 has a ±VREF fully differential input range with VREF ranging from 2.5V to 5.1V. The LTC2380-16 consumes only 19mW and achieves ±0.6LSB INL maximum, no missing codes at 16-bits with 96.2dB SNR.
The LTC2380-16 has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisy-chain mode. The fast 2Msps throughput with no cycle latency makes the LTC2380-16 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2380-16 automatically powers down between conversions, leading to reduced power dissipation that scales with the sampling rate.
The LTC2380-16 features a unique digital gain compression (DGC) function, which eliminates the driver amplifier’s negative supply while preserving the full resolution of the ADC. When enabled, the ADC performs a digital scaling function that maps zero-scale code from 0V to 0.1 • VREF and full-scale code from VREF to 0.9 • VREF. For a typical reference voltage of 5V, the full-scale input range is now 0.5V to 4.5V, which provides adequate headroom for powering the driving amplifier from a single 5.5V supply.
