General Description

Beneﬁts and Features

The

MAX40079/MAX40087/MAX40077/MAX40089/

● Low Input Voltage Noise Density: 4.2nV/√Hz at 30KHz

● Low Input Current Noise Density: 0.5fA/√Hz

● Low Input Bias Current: 0.3pA (typ)

MAX40078 are wide band, low-noise, low-input bias

current operational amplifiers that offer rail-to-rail outputs

and single-supply operation from 2.7V to 5.5V. These low-

noise amps draw 2.2mA of quiescent supply current per

amplifier. This family of amplifiers offers ultra-low distortion

(0.0002% THD+N), as well as low input voltage-noise

density (4.2nV/√Hz) and low input current-noise density

(0.5fA/√Hz). The low input bias current of 0.3pA (typ) and

low noise(4.5nV/√Hz), together with the wide bandwidth,

provides excellent performance for transimpedance (TIA)

and imaging applications.

● Low Distortion: 0.00035% or -109dB THD+N (1kΩ

Load)

● Single-Supply Operation from +2.7V to +5.5V

● Input Common-Mode Voltage Range Includes

Ground

● Rail-to-Rail Output Swings with a 1kΩ Load

● Wide Bandwidth: MAX40079/MAX40077/MAX40078

(10MHz); MAX40087/MAX40089 (42MHz)

● Excellent DC Characteristics: V

● Single-Channel 6-bump WLP in 1.31mm x 0.73mm

with 0.35mm Bump Pitch

● Dual-Channel 8-bump WLP in 0.96mm x 1.66mm

with 0.35mm Bump Pitch

● Available in Space-Saving 6-WLP, 6-SOT, 8-WLP

≤ 30μV

These amplifiers have outputs which swing rail-to-rail and

their input common-mode voltage range includes ground.

The MAX40079/MAX40077/MAX40078 are single/dual/

quad respectively in unity-gain stable with a bandwidth

of 10MHz. The MAX40087/MAX40089 are single/dual

respectively with gain ≥ 5 stable and bandwidth of 42MHz.

They operate over the full -40°C to +125°C temperature

range.

and μMAX Packages

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 μMAX-8 packages.

The quad channel option is available in 14-TSSOP package.
