The OPA347 (single version) is available in the SC-70 and SOT23-5 packages. The OPA2347 (dual version) is available in the SOT23-8 and WCSP-8 packages. Both are also available in the SO-8. The OPA347 is also available in the DIP-8. The OPA4347 (quad) is available in the SO-14 and the TSSOP-14. The small size and low power consumption (34 µA per chan- nel maximum) of the OPA347 make it ideal for portable and battery-powered applications. The input range of the OPA347 extends 200mV beyond the rails, and the output range is within 5mV of the rails. The OPA347 also features an excellent speed/power ratio with a bandwidth of 350kHz. The OPA347 can be operated with a single or dual power supply from 2.3V to 5.5V. All models are specified for operation from –55 °C to +125°C. ® OPA3 47 OPA3 47 OPA2 347 OPA4 347 OPA347 1 2 3 5 4 V+ –In Out V– +In OPA347 SOT23-5 1 2 3 4 8 7 6 5 NC V+ Out NC NC –In +In V– OPA347 SO-8, DIP-8 1 2 3 4 8 7 6 5 V+ Out B –In B +In B Out A –In A +In A V– OPA2347 SOT23-8, SO-8 A B 1 2 3 4 5 6 7 14 13 12 11 10 9 8 Out D –In D +In D V– +In C –In C Out C Out A –In A +In A V+ +In B –In B Out B OPA4347 TSSOP-14, SO-14 AD BC OPA347 OPA2347 OPA4347 SBOS167D – NOVEMBER 2000– REVISED JULY 2007 www.ti.com PRODUCTION DATA information is current as of publication date.
