POWER REQUIREMENTS

Supply Voltages

AVDD15

Maximum operating range of |AVDD1 to AVSS| =

60 V

AVDD2

Maximum operating range of |AVDD2 to AVSS| =

50 V

AVSS5

−33

Maximum operating range of |AVDD1 to AVSS| =

60 V; for bipolar output ranges, VOUT/IOUT head-

room must be obeyed when calculating AVSS

maximum; for unipolar current output ranges,

AVSS maximum = 0 V; for unipolar voltage

output ranges, AVSS maximum = −2 V

AVDD1 = 24 V, AVDD2 = 5 V, AVSS = −15 V, RLOAD =

1 kΩ, IOUT = 20 mA

AVDD1 = AVDD2 = 24 V, AVSS = −15 V, RLOAD = 1 kΩ,

IOUT = 20 mA

200

AVDD1 = AVDD2 = 24 V, AVSS = −15 V, RLOAD = 0 Ω,

IOUT = 20 mA

See the Current Output Mode section for more information about the internal and external RSET resistors.

The long-term stability specification is noncumulative. The drift in subsequent 1000 hour periods is significantly lower than in the first 1000 hour period.

Guaranteed by design and characterization; not production tested.

The ADFS5758 is factory calibrated with an external 2.5 V reference connected to REFIN.

Production tested to AVDD1 maximum = 30 V and AVSS minimum = −30 V.
