  • AD7194- 8-Channel, 4.8 kHz, Ultralow Noise, 24-Bit Sigma-Delta ADC with PGA
    AD7194: 8-Channel, 4.8 kHz, Ultralow Noise, 24-Bit Sigma-Delta ADC with PGA

    The AD7194 is a low noise, complete analog front end for high precision measurement applications. It contains a low noise, 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC). The on-chip low noise gain stage means that signals of small amplitude can interface directly to the ADC. The device can be configured to have eight differential inputs or sixteen pseudo differential inputs. The MoreRead more

  • AD7985- 16-Bit, 2.5 MSPS PulSAR 11 mW ADC in QFN
    AD7985: 16-Bit, 2.5 MSPS PulSAR 11 mW ADC in QFN

    The AD7985 is a 16-bit, 2.5 MSPS successive approximation analog-to-digital converter (SAR ADC). It contains a low power, high speed, 16-bit sampling ADC, an internal conversion clock, an internal reference (and buffer), error correction circuits, and a versatile serial interface port. On the rising edge of CNV, the AD7985 samples an analog input, IN+, between 0 V and REF with respect to a ground MoreRead more

  • AD7626- 16-Bit, 10 MSPS, PulSAR Differential ADC
    AD7626: 16-Bit, 10 MSPS, PulSAR Differential ADC

    The AD7626 is a 16-bit, 10 MSPS, charge redistribution successive approximation register (SAR) based architecture analog-to-digital converter (ADC). SAR architecture allows unmatched performance both in noise (91.5 dB SNR) and in linearity (±0.45 LSB INL). The AD7626 contains a high speed, 16-bit sampling ADC, an internal conversion clock, and an internal buffered reference. On the CNV edge, it MoreRead more

  • AD9277- Octal LNA/VGA/AAF/14-Bit ADC and CW I/Q Demodulator
    AD9277: Octal LNA/VGA/AAF/14-Bit ADC and CW I/Q Demodulator

    The AD9277 is designed for low cost, low power, small size, and ease of use. It contains eight channels of a variable gain amplifier (VGA) with a low noise preamplifier (LNA); an anti-aliasing filter (AAF); a 14-bit, 10 MSPS to 50 MSPS analog-to-digital converter (ADC); and an I/Q demodulator with programmable phase rotation.

    Each channel features a variable gain range of 42 dB, a fully MoreRead more
