产品详情

Demonstration circuit 2376A features the LTC2664, 4-channel 16-Bit/12-Bit ±10V V_OUT 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.
