The LTC2376-18 is a low noise, low power, high speed 18-bit successive approximation register (SAR) ADC. Operating from a 2.5V supply, the LTC2376-18 has a ±VREF fully differential input range with VREF ranging from 2.5V to 5.1V. The LTC2376-18 consumes only 3.4mW and achieves ±1.75LSB INL maximum, no missing codes at 18 bits with 102dB SNR.
The LTC2376-18 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 250ksps throughput with no cycle latency makes the LTC2376-18 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2376-18 automatically powers down between conversions, leading to reduced power dissipation that scales with the sampling rate.
The LTC2376-18 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 • 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.

DC1783A-H
LTC2376-18 with LTC6655-5/LT6350 Demo Board | 18-Bit, 250ksps, SAR ADC with 102dB SNR. Requires DC718 or DC2026
Product Detail
The LTC2380/LTC2379/LTC2378/LTC2377/LTC2376 are low power, low noise ADCs with serial outputs that can operate from a single 2.5V supply. The demo manual refers to the LTC2379-18 but applies to all parts in the family, the only difference being the maximum sample rates and the number of bits. The LTC2379-18 supports a ±5V fully differential input range with a 101dB SNR, consumes only 18mW and achieves ±2LSB INL max with no missing codes at 18-bits. The DC1783A demonstrates the DC and AC performance of the LTC2379-18 in conjunction with the DC590 QuikEval™ and DC718 PScope™ data collection boards.
