The SGM58600A, SGM58601A and SGM58602A are low noise, 24-bit, 60kSPS, delta-sigma (ΔΣ) analog-to-digital converters (ADCs).

The SGM58600A, SGM58601A and SGM58602A have a fourth-order delta-sigma modulator plus a fifth-order Sinc filter (Sinc⁵) optimized for low noise performance.

The flexible input multiplexer supports single-ended input or differential input configurations.

The SGM58600A, SGM58601A and SGM58602A 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 devices have an internal on-chip oscillator. It is switched on by default after the system powers up. The internal oscillator can be switched off by software and configured as an external clock source.

The SGM58600A is available in Green SSOP-20 and TQFN-3.5×3.5-20L packages, the SGM58601A is available in Green SSOP-28 and TQFN-5×5-28L packages, and the SGM58602A is available in a Green TQFN-5×5-20L package. They are all specified from -40℃ to +125℃.
