The SPT7853 offers significant advantages over discrete single-channel A/D implementations. Board area, package count, system cost and power dissipation can greatly be reduced by using a single SPT7853 device. In addition,several performance advantages exist, including low chan-nel to-channel cross-talk noise and well matched channel-to-channel gain specifications. The three analog-to-digital converters are driven from a common 2X sample rate CMOS clock.
The SPT7853 typically consumes only 580 mW of total power from a single +5 V supply.Digital outputs can operate with +3 V or +5 V logic and are tri-state capable.The SPT7853 is offered in a small 52-pin thin quad flat pack (TQFP) package and operates over the 0 to +70 commercial range.
