Description
Vendor Part Number

(1)
0.1
μ
F ceramic capacitor
Erie RPE112Z5U104M50V
C4–6
(2)
10
μ
F tantalum capacitor
Mallory CSR13G106KM
Notes: (1). A 0.1
μ
F capacitor should be connected
between each group
of power pins and ground as close to the de-
vice as possible, (ceramic chip capacitors are preferred).
(2). The 10
μ
F capacitors should be connected between the analog supply and the analog ground, as well as the
digital supply and the digital ground. These should be connected as close to the Bt848 as possible.
3. These vendor numbers are listed only as a guide. Substitution of devices with similar characteristics will not
affect the performance of the Bt848.
