ECJ3VB1A394K Datasheet NOTES: 1. Typical values are for TA = 25aC and 3.3V supply voltage. 2. LSB: [V(RW)127 - V(Rw)0]/127. V(RW)127 and V(Rw)0 are V(Rw) for the DCP register set t0 7F hex and 00 hex respectively. LSB is the incremental voltage when changing from one tap to an adjacent tap. 3. ZS error = V(Rw)O/LSB. 4. FS error = [V(RW)127 - V+]/LSB. 5. DNL = [V(RW)i - V(RW)i_l]/LSB-1, for i = 1 t0 127. i is the DCP register setting. 6. INL = V(RW)i - (i . LSB - V(Rw)0) for i = 1 t0 127. Max(V(RW)i) - Min(V(RW)i) 106 7. TCV = [Max(V(RW)i)+M (V RW )] ~2x1250C for i = 16 t0 120 decimal, T = -400C t0 85aC. Max( ) is the maximum value of the wiper voltage and Min ( ) is the minimum value of the wiper voltage over the temperature range. 8. Ml = IR127 - Rol /127. R127 and RO are the measured resistances for the DCP register set t0 7F hex and 00 hex respectively. 9. Roffset = Ro/MI, when measuring between Rw and RL. Roffset = R127/MI, when measuring between Rw and RH. 10. RDNL = (Ri - Ri_l)/MI, for i = 16 t0 127. 11. RINL = [Ri - (Ml . i) - Ro]/MI, for i = 16 t0 127. :(Ri)-Min(Ri)] x 106 12. TCR = [M[Mxa(R(R)+Min(Ri)]~2 1250C for i = 16 t0 127, T = -400C t0 850C. Max( ) is the maximum value of the resistance and Min ( ) is the minimum value of the resistance over the temperature range. 13. This parameter is not 100% tested. 14. twc is the minimum cycle time to be allowed for any non-volatile Write by the user, unless Acknowledge Polling is used. It is the time from a valid STOP condition at the end of a Write sequence of a 3-wire serial interface Write operation, to the end of the self-timed internal non-volatile write cycle.

Hys- teretic comparator Al determines if Vc is too low for the LT1619 to operate efficiently. As Vc falls below the trip voltage VB, Al's output goes high, turning off all blocks except the error amplifier, Al and A2. The LT1619 enters the idle state and switching stops. The device draws just 140aA from the input in the idle state.
