LTC2368-24 是一款低噪声、低功率、高速 24 位逐次逼近型寄存器 (SAR) ADC,其具有一个集成型数字平均滤波器。LTC2368-24 采用一个 2.5V 工作电源,具有 0V 至 VREF 的伪差分单极性输入范围 (VREF 的变化范围从 2.5V 至 5.1V)。LTC2368-24 仅消耗 21mW (典型值) 功率,并实现了 ±4.5ppm INL (最大值) 和无漏失码 (在 24 位)。
LTC2368-24 具有一个易用的集成型数字平均滤波器,该滤波器能够对 1 至 65536 个转换结果进行实时平均,并显著地把动态范围从 98dB (在 1Msps) 改善至 140dB (在 15.25sps)。不需要单独的编程接口或配置寄存器。
高速 SPI 兼容型串行接口支持 1.8V、2.5V、3.3V 和 5V 逻辑,同时还拥有一种菊链模式。LTC2368-24 在转换操作之间自动地断电,从而减少了较低采样速率条件下的功率耗散。

DC2289A-B:LTC2368-24 Demo Board | 24-Bit, 1Msps Pseudo-Differential Input SAR ADC with Integrated Filter (Requires DC590, DC2026 or DC890)
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.
