Dual-, Differential, Low-Pass Filter µModule with Gain and ADC Driver

The ADAQ8088 is a dual-channel analog system in package (SIP) that integrates three common signal processing and conditioning blocks to support a variety of demodulator applications and data acquisition applications. The device integrates all active and passive components to form a complete signal chain between the output of an I/Q demodulator and the input to an analog-to-digital converter (ADC). The device also forms the complete signal chain between a transducer output and the input to an ADC in baseband data acquisition systems. No external components are required for proper functionality.

Each channel contains a preamplifier, followed by an 8-pole, low-pass filter with a 36 MHz, 3 dB frequency and a differential ADC driver optimized to drive 12-bit to 14-bit pipeline ADCs with speeds up to 150 MSPS. Encapsulated in a 6 mm × 12 mm CSPBGA package, the ADAQ8088 minimizes space requirements in high density multichannel systems.

The ADAQ8088 operating temperature range is from −40°C to +85°C.
