MAX40079/MAX40087/ Single/Dual/Quad Ultra-Low MAX40077/MAX40089/ Input Bias Current, Low-Noise Amplifiers MAX40078 General Description Benefits and Features The MAX40079/MAX40087/MAX40077/MAX40089/ Low Input Voltage Noise Density: 4.2nV/Hz at 30KHz MAX40078 are wide band, low-noise, low-input bias Low Input Current Noise Density: 0.5fA/Hz current operational amplifiers that offer rail-to-rail outputs Low Input Bias Current: 0.3pA (typ) and single-supply operation from 2.7V to 5.5V. These low- Low Distortion: 0.00035% or -109dB THD+N (1k noise amps draw 2.2mA of quiescent supply current per Load) amplifier. This family of amplifiers offers ultra-low distortion Single-Supply Operation from +2.7V to +5.5V (0.0002% THD+N), as well as low input voltage-noise Input Common-Mode Voltage Range Includes density (4.2nV/Hz) and low input current-noise density Ground (0.5fA/Hz). The low input bias current of 0.3pA (typ) and Rail-to-Rail Output Swings with a 1k Load low noise(4.5nV/Hz), together with the wide bandwidth, Wide Bandwidth: MAX 40079/MAX40077/MAX40078 provides excellent performance for transimpedance (TIA) (10MHz) MAX40087/MAX40089 (42MHz) and imaging applications. Excellent DC Characteristics: V 30V OS These amplifiers have outputs which swing rail-to-rail and Single-Channel 6-bump WLP in 1.31mm x 0.73mm their input common-mode voltage range includes ground. with 0.35mm Bump Pitch The MAX40079/MAX40077/MAX40078 are single/dual/ quad respectively in unity-gain stable with a bandwidth Dual-Channel 8-bump WLP in 0.96mm x 1.66mm with 0.35mm Bump Pitch of 10MHz. The MAX40087/MAX40089 are single/dual respectively with gain 5 stable and bandwidth of 42MHz. Available in Space-Saving 6-WLP, 6-SOT, 8-WLP They operate over the full -40C to +125C temperature and MAX Packages range. THD+N Performance Single channel op amps are available in 6-bump wafer-level package (WLP) and SOT23 6-pin packages. The dual channel op amps are available in 8-bump WLP and MAX-8 packages.
