The fully-differential configuration is illustrated in Figure 10, with the corre- sponding transfer function illustrated in Figure 11. INPUT DRIVE CIRCUITS A low impedance source can directly drive the high imped- ance inputs of the LTC2321-16 without gain error. A high impedance source should be buffered to minimize set- tling time during acquisition and to optimize the distortion performance of the ADC. Minimizing settling time is important even for DC inputs, because the ADC inputs draw a current spike when during acquisition. For best performance, a buffer amplifier should be used to drive the analog inputs of the LTC2321-16. The amplifier provides low output impedance to minimize gain error and allow for fast settling of the analog signal during the acquisition phase. It also provides isolation between the signal source and the ADC inputs, which draw a small current spike during acquisition. 25 25 220pF VREF 0V VREF 0V VREF 0V VREF 0V ONLY CHANNEL 1 SHOWN FOR CLARITY + – + – LTC2321-16 LT1819 232116 F10 SDO1 VBYP1 REFOUT1 CLKOUT AIN1– AIN1+ SCK TO CONTROL LOGIC (FPGA, CPLD, DSP, ETC.) 1µF 10µF 232116 F11 –VREF –16384 16383 –32768 32767 VREF AIN (AINn+ – AINn–) ADC CODE (2’s COMPLEMENT) –VREF/2 VREF/2 0 Figure 10.
