Features and benefits

• Full dielectric isolation (DI) and high ESD cells (>4kV ESD

HBM) provide highly robust inputs compared to older

process amplifiers.

• Thin film resistors and fuse-link trim cells offer very low

offset voltages (Figure 2)

Features

• Very Low Voltage Noise.........................................2.5nV/√Hz

• Low Input Offset....................................................70μV, Max.

• Superb Offset Drift ........................................0.5μV/°C, Max.

• Wide Supply Range..............................................4.5V to 40V

• Gain-bandwidth Product................10MHz Unity Gain Stable

• Outstanding ESD Performance

- Human Body Model: 4.0kV

Precision high voltage op amps were developed on

Intersil’s new PR40 process. PR40 is a new precision

process that enables Intersil to develop competitive

precision high voltage amplifiers. Key features of the

new process are full DI, complementary bipolar, low

noise, well-matched Super-beta transistors, P-channel

JFET, high breakdown voltage (>44V), high density

capacitors, Thin Film resistors, fuse-link trim cells, and

high ESD cells. (Figure 1)

Intersil’s ISL28127 is a high voltage precision op amp,

delivering low frequency noise, low distortion, ultra low

offset and low drift offset.
