Teledyne DALSA Unveils Sample + Hold Precision Linear Amplifier IC for MOEMS and MEMS Systems

Teledyne DALSA Semiconductor, a company of Teledyne Technologies, has introduced DH9665A, a sample & hold precision linear amplifier integrated circuit (IC) for high-density MEMS and MOEMS systems.

Teledyne DALSA's DH9665A Sample & Hold Precision Linear Amplifier Integrated Circuit

The DH9665A is based on Teledyne DALSA Semiconductor’s in-house high-voltage CMOS/DMOS technology. It is specially developed for next-generation, low-power, small footprint, high-density systems that use MOEMS or MEMS activation with electrostatic forces. This new device demonstrates the company’s portfolio of product design and production capabilities for HV-CMOS, CCD and MEMS systems.

The DH9665A offers a cost-saving solution for high density systems and broadens Teledyne DALSA's proven capabilities for MEMS and MOEMS. It delivers a broad range of liner output of up to 240 V with a voltage accuracy of ±20 mV on 96 sample & hold amplifiers that operate independently. The RoHS-compliant device is offered in either as a bumped die having a footprint area of 0.8 mm2 per channel or in a BGA package with dimensions of 17x17 mm.

The DH9665A features 4 simultaneously programmable analog HV outputs, with 24 selectable groups. Its internal closed loop gain is 79V/V and consumes power less than 500 mW. It has a built-in diode to monitor temperatures and has single polarity low-voltage power supplies. Its power up or down configuration is comparatively simpler than the Supertex HV257. It consumes less power and features three folds more channels than the Supertex HV257 for the same size.

Teledyne DALSA’s Senior Product Manager, Remi Meingan informed that the advanced high-voltage design allows the company to deliver very low power consumption where more number of channels is required.
