For IOUT, RL = 300 Ω. Typical specifications are at 25°C. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT (3) Specified by design and characterization; not production tested. (4) Loop compliance voltage is defined as the voltage at the IOUT terminal. (5) For stability, use slew rate limit feature or add a capacitor between IOUT and GND CURRENT OUTPUT ACCURACY (4 mA TO 20 mA)(1) Total unadjusted error, TUE Internal RSET TA = –40°C to 125°C –0.25% 0.25% FSR TA = 25°C –0.08% ±0.02% 0.08% External RSET TA = –40°C to 125°C –0.29% 0.29% TA = –40°C to 85°C –0.25% 0.25% TA = 25°C –0.1% ±0.02% 0.1% Differential nonlinearity, DNL Monotonic ±1 LSB Relative accuracy, INL(2) TA = –40°C to 125°C ±0.08% FSR TA = –40°C to 85°C ±0.024% Offset error Internal RSET TA = –40°C to 125°C –0.22% 0.22% FSR TA = –40°C to 85°C –0.2% 0.2% External RSET TA = –40°C to 125°C –0.2% 0.2% TA = –40°C to 85°C –0.18% 0.18% Internal and external RSET, TA = 25°C –0.07% ±0.01% 0.07% Offset error temperature coefficient ±3 ppm FSR/°C Full-scale error Internal RSET TA = –40°C to 125°C –0.25% 0.25% FSR TA = 25°C –0 .08% ±0.015% 0.08% External RSET TA = –40°C to 125°C –0.29% 0.29% TA = –40°C to 85°C –0.25% 0.25% TA = 25°C –0 .1% ±0.015% 0.1% Full-scale error temperature coefficient Internal RSET ±5 ppm FSR/°C External RSET ±10 Gain error Internal RSET TA = –40°C to 125°C –0.2% 0.2% FSR TA = –40°C to 85°C –0.15% 0.15% TA = 25°C –0.08% ±0.01% 0.08% External RSET TA = –40°C to 125°C –0.16% 0.16% TA = –40°C to 85°C –0.12% 0.12% TA = 25°C –0.05% ±0.01% 0.05% Gain error temperature coefficient Internal RSET ±3 ppm FSR/°C External RSET ±8 Output current drift vs time TA = 125°C, 1000 hrs Internal RSET ±50 ppm FSR External RSET ±75 CURRENT OUTPUT STAGE(3) Loop compliance voltage(4) Output = 24 mA AVDD – 2 V Inductive load(5) 50 mH DC PSRR 1 μA/V Output impedance Code = 0x8000 50 MΩ R3 RESISTOR R3 resistor value 36 40 44 Ω R3 resistor temperature coefficient 40 ppm/°C EXTERNAL REFERENCE INPUT Reference input voltage 4.95 5 5.05 V External reference current REFIN = 5.0 V 30 μA Reference input capacitance 10 pF |
