Ltc2338/ltc2337/ltc2336/ Ltc2328/ltc2327/ltc2326 18-bit/16-bit,1msps/500ksps/250ksps True Bipolar
Low Power, Single Supply ADCs
Description
The Ltc 2338/ltc2337/ltc2336/ltc2328/ltc2327/ Ltc2326 Are True Bipolar, Low Power, Low Noise Adcs
With Serial Outputs That Can Operate From A Single 5v Supply. The Following Text Refers To The
Ltc2338-18 But Applies To All Parts In The Family, The Only Difference Being The Maximum Sample
Rates And The Number Of Bits. The Ltc2338-18 Supports A 20.48v Fully Differential Input Range With
A 100db Snr, Consumes Only 50mw And Achieves 4lsb Inl Max With No Missing Codes At 18 Bits. The
Dc1908a Demonstrates The Dc And Ac Performance Of The Ltc2338-18 In Conjunction With The Dc590
Quikeval And Dc718 Pscope Data Collection Boards. Use The Dc590 To Demonstrate Dc Performance Such
as
Peak-to-peak Noise And Dc Linearity. Use The Dc718 If Precise Sampling Rates Are Required Or To
Demonstrate Ac Performance Such As Snr, Thd, Sinad And Sfdr. The Demonstration Circuit 1908a Is
Intended To Demonstrate Recommended Grounding, Component Placement And Selection, Routing And
Bypassing For This Adc. Suggested Driver Circuits For The Analog Inputs Will Be Presented.
L, Lt, Ltc, Ltm, Linear Technology And The Linear Logo Are Registered Trademarks And Quikeval,
Pscope Are Trademarks Of Linear Technology Corporation. All Other Trademarks Are The Property Of
their respective owners.
