... This easy-to-use device includes sample-and- hold, precision reference, switched capacitor successive approximation A/D and trimmed internal clock. The LTC1606’s input range is an industry standard 10V. Maximum DC specs include 2.0LSB INL and 16 bits no missing codes over temperature. An external reference can be used if greater accuracy over temperature is needed ...

... Pin 15 and bit 8 is output on Pin 22. Bit 7 is output on Pin 6 and the LSB is output on Pin 13. R/C (Pin 24): Read/Convert Input. With CS low, a falling edge on R/C puts the internal sample-and-hold into the hold state and starts a conversion. With CS low, a rising edge on R/C enables the output data bits.

... DAC Figure 1. LTC1606 Simplified Equivalent Circuit W U Driving the Analog Inputs The nominal input range for the LTC1606 is 10V • V REF The input impedance is typically 10k , therefore, it should be driven with a low impedance source. Wideband noise coupling into the input can be minimized by placing a 1000pF capacitor at the input as shown in Figure 2 ...

... F tantalum for the REF pin and 10 F tantalum for the CAP pin). Offset and Gain Adjustments The LTC1606 offset and full-scale errors have been trimmed at the factory with the external resistors shown in Figure 4. This allows for external adjustment of offset and full scale in applications where absolute accuracy is impor- tant ...
