*Multi-purpose linear amplifiers for commercial and industrial applications.
*Less than 0.5o2 harrnonic distortion at f ull power level.
*L/2dB response trom 20 to 100,000H2.
* Built-in current limiting (f or S1.1030c & Sl-1050G) and ef f icient heat
radiating construction.
rrSingle or split (dual) power supply.
* Rugged, compact and light weight packages.
SANKEN Series Sl-1000G amplifiers are self-contained power hybrid amplifiers
designed f or Hi-Fi, stereo, musical instruments, public address systems
and other audio applicatiqns. The amplif iers have quasi-complementary class
B output. The circuit employs f lip-chip transistors with high reliability and
passivated chip power transistors with excellent secondary breakdown
strength. Built-in current limiting is provided for Sl-1030G and Sl-1050G.
The device can be operated from a single or split power supply.
