DC2197A-A

DC2197A-A is a LTC2645 quad 12-/10-/8bit PWM to VOUT DACs with 10ppm/°C reference demonstration board. The LTC2645 measures the period and pulse width of the Pulse Width Modulation (PWM) input and updates the voltage output DAC at each rising edge. The PWM frequency can be any frequency between 30Hz and 100KHz. The input level can be between 1.71V and 5.5V, set by a separate IOVCC pin. This device solves many of the problems associated with filtering a PWM signal to produce an analogue voltage, producing a fast-settling, accurate analogue voltage in response to a digital PWM input.

• DC2197A makes evaluation of the LTC2645 very easy
• DC2197A as a standalone board
• DC2197A is an "Arduino Shield" form factor, compatible with DC2026 Linduino board
