• Manufacturer: Semtech

Specifications of E6420BBG

• Lead Free Status / RoHS Status: Not Compliant

Chip Overview
The Edge6420 provides 64 output levels (44 voltage and
20 current). These outputs can easily be configured to
generate the specific analog voltage and current
requirements for 4 channels of ATE pin electronics
including:
without requiring any scaling or shifting via external
components.
The Edge6420 has the flexibility to be used in other
configurations for other applications.
Programming of the chip is done using a 4 bit digital
interface comprised of:

The max DAC range is achieved through specific AVCC, AVEE, and Gain resistor settings. See the
equations in the "DAC Voltage Output Overview", "DAC Current Output Overview", and specifications for details.
–128 LSB is equivalent to –128 * LSB, where LSB = Range / 2
this offset would thus be: –56.26 A of offset current at Code 0.
Compliance specified in the table is at IOUT = 1.3mA. Maximum compliance is lower at higher currents.
Please refer to specifications for compliance at other output currents.
