The Infrared Array Camera for the Space Infrared Telescope Facility (SIRTF/IRAC) is capable of two-dimensional photometry in either a wide field or diffraction-limited mode over the wavelength interval from 2 to 30 microns. Three different two-dimensional direct readout (DRO) array detectors are being considered: Band 1 - InSb or Si:In (2 - 5 microns) 128 x 128 pixels, Band 2 - Si:Ga (5 - 18 microns) 64 x 64 pixels, and Band 3 - Si:Sb (18 -30 microns) 64 x 64 pixels. The hybrid DRO readout architecture has the advantages of low read noise, random pixel access with individual readout rates, and non-destructive readout. The scientific goals of IRAC are discussed, which are the basis for several important requirements and capabilities of the array camera: 1) diffraction-limited resolution from 2 - 30 microns, 2) use of the maximum unvignetted field of view of SIRTF, 3) simultaneous observations within the three infrared spectral bands, 4) the capability for broad and narrow bandwith spectral resolution. A strategy has been developed to minimize the total electronic and environmental noise sources to satisfy the scientific requirements.
