SGM51620R

The SGM51620R is a precise 16-bit analog-to-digital converter (ADC) designed to minimize system costs and component count in applications involving the measurement of small sensor signals. It features four single-ended inputs or two differential inputs through a versatile input multiplexer (MUX), a low-noise programmable gain amplifier (PGA), two programmable excitation current sources, a voltage reference, an oscillator, a low-side switch, and a detailed temperature sensor. 

The SGM51620R is capable of achieving conversions at data rates up to 2000 samples per second (SPS) with single-cycle settling. The device's digital filter operates at 20SPS, effectively rejecting 50Hz and 60Hz frequencies in noisy industrial environments. The internal PGA provides amplification levels up to 128V/V, making the SGM51620R suitable for measuring delicate sensor signals such as resistance temperature detectors (RTDs), thermocouples, thermistors, and resistive bridge sensors. The device supports the measurement of pseudo-differential or fully-differential signals when the PGA is used. Alternatively, it can be configured to bypass the internal PGA while still offering high input impedance and amplification levels up to 4V/V, facilitating single-ended measurements. 

In duty-cycle mode with the PGA deactivated, the power consumption drops to a minimal 175μA. 

The SGM51620R is available in Green TSSOP-16 and TQFN-3.5×3.5-16L packages, and it is suitable for an extended temperature range from -40℃ to +125℃.
