DESCRIPTION

· The AD7134 is a 24-bit, 4-channel simultaneous sampling ADC with a 1.5 MSPS precision alias-free performance.

· It features inherent anti-alias rejection and supports high-performance mode with 102.5 dB typical rejection.

· The device offers excellent AC and DC performance, with a dynamic range of 108 dB at ODR = 374 kSPS and 137 dB at ODR = 10 SPS.

· It includes programmable data rates from 0.01 kSPS to 1.496 kSPS with a resolution of 0.01 SPS.

· The ADC supports multidevice synchronization with one signal line and has two power modes: high performance and low power.

· It operates with a power supply of 4.5 V to 5.5 V and 1.65 V to 1.95 V, and is available in an 8 mm × 8 mm, 56-lead LFCSP package.
