MAX4070AUA+

Maxim Integrated · Pre-ordered Chips · MSOP-8

MAX4070AUA+ from Maxim Integrated, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SHDN input Shutdown input: drive low to select shutdown mode (about 10µA supply current), connect to VCC for normal operation; logic low VIL max 0.6V and logic high VIH min 2V at VCC = 3.6V or 24V.
2 RS- input Negative connection to the external sense resistor; common-mode input range is 1.35V to 24V and the differential input voltage absolute maximum is ±0.3V.
3 RS+ input Positive connection to the external sense resistor; common-mode input range is 1.35V to 24V and the differential input voltage absolute maximum is ±0.3V.
4 GND power_in Ground reference for the device; the pin is the device ground and all output voltages are referenced to it.
5 REFOUT output Internal 2.5V reference output for the MAX4070 (2.45V to 2.55V at 25°C, VCC = 12V); it can sink 100µA and source 500µA, and total capacitance on it must stay under 500pF for stability.
6 OUT output Voltage output where VOUT - VREF is proportional to VSENSE and indicates polarity; it goes high impedance in shutdown and its absolute maximum is the lesser of (VCC + 0.3V) or 15V relative to GND.
7 VCC power_in Supply voltage input for the MAX4070, operating from 3.6V to 24V; bypass VCC to GND with a 0.1µF capacitor.
8 GSEL input Gain-select input: connect low to select gain = 50V/V, or high to select gain = 100V/V; logic low VIL max 0.6V and logic high VIH min 2V at VCC = 3.6V or 24V.
