The LTC2666 is a family of 8-channel, 16-/12-bit ±10V digital-to-analog converters with integrated precision references. They are guaranteed monotonic and have built-in rail-to-rail output buffers. These SoftSpan DACs offer five output ranges up to ±10V. The range of each channel is independently programmable, or the part can be hardware-configured for operation in a fixed range.

The integrated 2.5V reference is buffered separately to each channel; an external reference can be used for additional range options. The LTC2666 also includes A/B toggle capability via a dedicated pin or software toggle command.

The SPI/Microwire-compatible 3-wire serial interface operates on logic levels as low as 1.71V at clock rates up to 50MHz.

LTC2666-16 Demo Board | 8-Channel 16-Bit ±10V VOUT SoftSpan DAC with 10ppm/°C Max Reference (requires DC2026 or DC590)

Product Detail

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.
