GENERAL DEscriptION
The SGM8604-1 (single), SGM8604-3 (single with shutdown), SGM8604-2 (dual) and SGM8604-5 (dual with shutdown) are low noise, high precision CMOS operational amplifiers that provide a high output current of 232mA, rail-to-rail output operation from a range of 2.7V to 5.5V single supply. The SGM8604-3/5 are both available with shutdown pins that drive the output voltage low.
The SGM8604-1/2/3/5 offer low input offset voltage, low input offset voltage drift and high output current drive. These devices also can achieve a high 15MHz gain-bandwidth product and a high 7V/μs slew rate.
The SGM8604-1/2/3/5 are specifically designed to drive high current load, such as 32Ω headset, VBIAS of RF power amplifier, etc.
The SGM8604-1/3 are available in a Green UTDFN-1.45×1-6L package. The SGM8604-2 is available in a Green TDFN-2×3-8AL package. The SGM8604-5 is available in a Green TDFN-3×3-10L package. They operate over an ambient temperature range of -40℃ to +125℃.
