The LTC2368-24 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 LTC2368-24 has a 0V to VREF pseudo-differential unipolar input range with VREF ranging from 2.5V to 5.1V. The LTC2368-24 consumes only 21mW (Typ) and achieves ±4.5ppm INL maximum and no missing codes at 24 bits.
The LTC2368-24 has an easy to use integrated digital averaging filter that can average 1 to 65536 conversion results real-time, dramatically improving dynamic range from 98dB at 1Msps to 140dB at 15.25sps. 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 daisy-chain mode. The LTC2368-24 automatically powers down between conversions, reducing power dissipation at lower sampling rates.

Evaluation Kits (1)
The LTC2380-24 and LTC2368-24 are low power, low noise, high speed, 24-bit SAR ADCs with an integrated digital averaging filter that operates from a single 2.5V supply. The demo manual refers to the LTC2380-24 but applies to both parts, the only difference being that the LTC2380-24 has fully differential inputs and the LTC2368-24 has pseudo-differential inputs. The LTC2380-24 has –117dB THD, consumes only 28mW and achieves ±4ppm INL max with no missing codes at 24 bits. The DC2289A demonstrates the DC and AC performance of the LTC2380-24 in conjunction with the DC590 or DC2026 QuikEval™ and DC890 PScope™ data collection boards. Use the DC590 or DC2026 to demonstrate DC performance such as peak-to-peak noise and DC linearity. Use the DC890 if precise sampling rates are required or to demonstrate AC performance such as SNR, THD, SINAD and SFDR. The Demonstration Circuit 2289A is intended to show recommended grounding, component placement and selection, routing and bypassing for this ADC.
Software & Systems Requirements
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
