TDA7237
QUAD DIFFERENTIAL LINE DRIVER
PRODUCT PREVIEW
DESCRIPTION
The quad differential line driver is a monolithic in-
tegrated circuit intended to provide low noise, low
distortion voltage gain.
Additionally, the signal is converted from a single
ended to a differential signal pair for applications
reuiring signal isolation from DC grounded.
The four channel鈥檚 gains are matched within 1dB.
