The ISL1539A provides 4 internal wideband op amps intended to be used as two pairs of differential line drivers. The ISL1539A's high bandwidth, 240MHz, and ultra low distortion, -89dBc @ 1MHz, 2VP-P, support the demanding MTPR requirements of emerging VDSL2 line driver designs. Less demanding requirements can be met at very low quiescent powers using the supply current adjustment features.
