5 Description (continued)

The TLV854x op amps operates with a single supply voltage down to 1.7 V supply, providing continuous

performance in low battery situations over the extended temperature range of –40°C to +125°C. All versions are

specified for operation from –40°C to 125°C. The TLV8541 (single version) is available in the 5-pin SOT-23 while

the TLV8542 (dual version) is available in the 8-pin SOIC package. The 4-channel TLV8544 (quad version) is

available in the industry standard 14-pin TSSOP package.
