General Description
The EL6265C consists of 13 fast settling, switch gain, trans-imped-
ance amplifiers with source terminated flex drive capability. The
amplifier bandwidth and settling times varies with the selected gain.
The fast channel bandwidths are 59MHz, 43MHz, and 34MHz. With a
short flex, the bandwidths can be slightly increased.
The EL6265C is designed to amplify the photo diode currents for CD,
DVD, or other photo diode pick-up applications.
Two TTL/CMOS compatible inputs select the gain for all eight ampli-
fiers. The gain settings are 12k
, 23k
,
and 63k
for all channels.
Gain matching is typically 3%, channel to channel. An auto-zero input
brought high after power up reduces the output offsets to less than
10mV.
Each amplifier output can typically sink or source up to 5mA and their
outputs can swing 1V
P-P
at full bandwidth at the end of a long flex cir-
cuit. The EL6265C operates from a single +5V supply and is available
in an LPP-38 package. It is specified for operation from -0
C to 7
