LTC2666 是一个 8 通道、16 位 / 12 位、±10V 数模转换器系列,其具有集成型高精度基准。这些器件保证具备单调特性,并具有内置的轨至轨输出缓冲器。这些 SoftSpan DAC 提供了 5 种输出范围 (最高达 ±10V)。每个通道的范围可单独设置,或者,也可以针对某种固定范围内的运作对器件进行硬件配置。
集成型 2.5V 基准单独缓冲至每个通道;一个外部基准可用于提供附加的范围选项。另外,LTC2666 还具备通过一个专用引脚或软件切换命令实现的 A/B 切换能力。
可兼容 SPI / Microwire 的三线式串行接口可依靠低至 1.71V 的逻辑电平在高达 50MHz 的时钟速率下操作。

DC2196A-B:LTC2666-12 Demo Board | 8-Channel 12-Bit ±10V VOUT SoftSpan DAC with 10ppm/°C Max Reference (requires DC2026 or DC590)
Demonstration circuit 2196A features the LTC2666, 8-channel 16-Bit/12-Bit ±10V VOUT SoftSpan DACs with 10ppm/°C max reference in a 5mm × 5mm QFN package. This device features per-channel SoftSpan configuration with five output ranges: 0V to 5V, 0V to 10V, ±2.5V, ±5V, and ±10V. A toggle feature allows any or all DACs to switch between two programmed codes via a single SPI command or by the TGP input pin. The versatile SPI interface can operate on any logic level between 1.71V and 5.5V, for easy interface to lower voltage microcontrollers or FPGAs.
