All devices have a gain-bandwidth product of MAX4461UESA -40°C to +85°C 8 SO — 2.5MHz. MAX4461TETT+T -40°C to +85°C 6 TDFN-EP* +ANK These amplifiers operate with a single-supply voltage MAX4461TEUT-T -40°C to +85°C 6 SOT23-6 AASU from 2.85V to 5.25V and with a quiescent current of only MAX4461TESA -40°C to +85°C 8 SO — 700µA (less than 1µA in shutdown for the MAX4461). The MAX4461HETT+T -40°C to +85°C 6 TDFN-EP* +ANL MAX4462 can also be operated with dual supplies. Smaller than most competitors, the MAX4460/ MAX4461HEUT-T -40°C to +85°C 6 SOT23-6 AASV MAX4461/MAX4462 are available in space-saving 6-pin MAX4461HESA -40°C to +85°C 8 SO — SOT23 and TDFN packages. +Denotes lead-free package.
