Description
General part information
LTC2378-16 Series
The LTC2378-18 is a low noise, low power, high speed 18-bit successive approximation register (SAR) ADC. Operating from a 2.5V supply, the LTC2378-18 has a ±VREFfully differential input range with VREFranging from 2.5V to 5.1V. The LTC2378-18 consumes only 13.5mW and achieves ±1.75LSB INL maximum, no missing codes at 18 bits with 102dB SNR.The LTC2378-18 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 1Msps throughput with no cycle latency makes the LTC2378-18 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2378-18 automatically powers down between conversions, leading to reduced power dissipation that scales with the sampling rate.The LTC2378-18 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 • VREFand full-scale code from VREFto 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.ApplicationsMedical ImagingHigh Speed Data AcquisitionPortable or Compact InstrumentationIndustrial Process ControlLow Power Battery-Operated InstrumentationATE
