The SGM58600, SGM58601 and SGM58602 are low noise, 24-bit, 60kSPS, delta-sigma (ΔΣ) analog-to-digital converters (ADCs).
The SGM58600, SGM58601 and SGM58602 have a fourth-order delta-sigma modulator plus a fifth-order Sinc filter (Sinc5) optimized for low noise performance.
The flexible inputs multiplexer supports single-ended input or differential input configuration.
The SGM58600, SGM58601 and SGM58602 feature a selectable input buffer that increases the input impedance, and the low noise programmable gain amplifier (PGA) provides gains from 1 to 128 in binary steps.
The devices have an SPI-compatible interface.
The SGM58600 is available in Green SSOP-20 and TQFN-3.5×3.5-20L packages, the SGM58601 is available in Green SSOP-28 and TQFN-5×5-28L packages, and the SGM58602 is available in a Green TQFN-5×5-20L package. They are all specified from -40℃ to +125℃.
