µV

PPMU enabled in FIMV, Range B, channel

under test: force 0.0 mA into 0.0 V; other

channel: force 0.0 mA into VDUTx; sweep

VDUTx from −1.5 V to +4.5 V; measure ∆V at

PPMU_Mx under test

%FSR

PPMU enabled in FVMI, Range B; channel

under test: force 0.0 V into open circuit;

other channel: force 0.0 V into IDUTx; sweep

IDUTx from −1.0 mA to +1.0 mA; measure ∆V

at PPMU_Mx under test

PCHx offset is derived from measurements at DAC Code 0xA000 (3.75 V or 50% FS) and DAC Code 0xB333 (4.50 V or 80% FS), with PCLx at DAC Code 0x0000 (−2.5 V).

PCLx offset is derived from measurements at DAC Code 0x6000 (1.25 V or −50% FS) and DAC Code 0x4CCC (0.50 V or −80% FS), with PCHx at DAC Code 0xFFFF (7.5 V).

PCHx gain is derived from the measurements at DAC Code 0xA000 (3.75 V or 50% FS) and DAC Code 0xB333 (4.50 V or 80% FS), with PCLx at DAC Code 0x0000

(−2.5 V). PCLx gain is derived from measurements at DAC Code 0x6000 (1.25 V or −50% FS) and DAC Code 0x4CCC (0.50 V or −80% FS), with PCHx at DAC Code 0xFFFF

(7.5 V). For example, the ideal gain is ±FS per 2.5 V in all ranges; in Range B, the ideal gain is ±400 µA/V; therefore, 30% error is ±520 µA/V.
