3 Description

The RES60A-Q1 is a matched resistive divider,

implemented in thin-film SiCr with Texas Instruments'

modern, high-performance, analog wafer process.

A high quality SiO2 insulative layer encapsulates

the resistors and enables usage at extremely high

voltages, up to 1400VDC for sustained operation or

4000VDC for HiPOT testing (60s). The device has a

nominal input resistance of RHV = 12.5MΩ, and is

available in several nominal ratios to meet a wide

array of system needs.

The RES60A-Q1 series features high ratio matching

precision, with the measured ratio of each divider

within ±0.1% (max) of the nominal. This precision is

maintained over the specified temperature range and

aging, with a cumulative drift of only ±0.2% (max).

Therefore, the lifetime tolerance of an uncalibrated

RES60A-Q1 remains within a ±0.3% (max) envelope.

The RES60A-Q1 is automotive qualified under

AEC-Q200 temperature grade 1, with a specified

temperature range from –40°C to +125°C. The device

is offered in an 8-pin SOIC package, with nominal

body size 7.5mm × 5.85mm, and features creepage

and clearance distances of at least 8.5mm between

the high-voltage and low-voltage pins.
