SGM58600/SGM58601/SGM58602
Ultra-Low Noise,
24-Bit Analog-to-Digital Converters
GENERAL DESCRIPTION
FEATURES
The SGM58600, SGM58601 and SGM58602 are low noise,
24-bit, 60kSPS, delta-sigma (ΔΣ) analog-to-digital converters
(ADCs).
● Supply Voltage Ranges:
Analog Supply: 5V
Digital Supply: 2.7V to 5V
● Noise-Free Resolution: Up to 22 Bits
● Data Output Rate: Up to 60kSPS
● Integral Nonlinearity (INL):
The SGM58600, SGM58601 and SGM58602 have
a
fourth-order delta-sigma modulator plus a fifth-order Sinc filter
(Sinc5) optimized for low noise performance.
0.0012%FSR (TYP) at PGA = 1
● 24-Bit No Missing Codes
The flexible inputs multiplexer supports single-ended input or
differential input configuration.
● Fast Channel Cycling
18.3 Bits Noise-Free (21.2 Effective Bits) at 1.4kHz
● Flexible Input Multiplexer
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.
2 Single-Ended Inputs or 1 Differential Inputs
(SGM58600)
8 Single-Ended Inputs or 4 Differential Inputs
(SGM58601)
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℃.
3 Single-Ended Inputs or 2 Differential Inputs
(SGM58602)
● Low Noise Programmable Gain Amplifier:
30nV Input-Referred Noise
● One-Shot Conversions with Single-Cycle Settling
● Chopper-Stabilized Input Buffer
● Supports Self and System Calibration for All PGA
Settings
● Supports SPI-Compatible Serial Interface

OVERSTRESS CAUTION
ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.

ESD Susceptibility
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failure to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

NOTES:
1. SPS = Samples Per Second.
2. FSR = Full-Scale Range = 4VREF/PGA.
3. fCM = Common-Mode Input Signal Frequency.
4. Setting a digital filter notch at 60Hz (fDATA = 60SPS, 30SPS, 15SPS, 10SPS, 5SPS, or 2.5SPS), this can improve the
common-mode rejection of this frequency.

single-ended inputs. The SGM58602 provides 4 analog
inputs, which can be configured as 2 independent differential
inputs, 3 single-ended inputs. When using the SGM58600 or
SGM58602 programming the inputs, make sure to select only
the available inputs when programming the input multiplexer
control register (MUX).
Overview
The SGM58600, SGM58601 and SGM58602 are ultra-low
noise analog-to-digital converters (ADCs). The block diagram
of the SGM5860x ADCs is shown in Figure 4.
The SGM58600 supports 1 differential input or 2 single-ended
inputs and has
SGM58601 supports 4 differential inputs or 8 single-ended
inputs and has general-purpose digital I/Os. The
2 general-purpose digital I/Os. The
To minimize the power consumption of the chip, it’s better to
keep any unused inputs floating.

circuits, in which RSENS is the sensor equal output impedance.
Please note that when the SDCS (Sensor Detection Current
Source) is enabled, the input buffer is forced on regardless of
BUFEN bit setting.
Noise Performance
The typical noise performance with the inputs shorted
externally is summarized from Table 1 to Table 6. For the six
tables, the following conditions apply: TA = +25℃, VAVDD = 5V,
VDVDD = 3.3V, VREF = 2.5V, and fCLKIN = 7.68MHz. ENOB is
given by:

Analog Input Buffer
1. Positive inputs minus negative inputs is the voltage range and at
the same time to make sure that both positive inputs and negative
inputs are absolutely positive respect to ground (listed in the
Electrical Characteristics section).
To increase the input impedance of SGM5860x, the input
buffer can be enabled by the BUFEN bit in the STATUS
register. The input impedance equal circuits are shown in
Figure 6. Table 9 lists the values of Zeff for the different PGA
settings. The equal input impedance changes inversely with
the CLKIN frequency (fCLKIN). For example, when the fCLKIN is
reduced by half to 3.84MHz, Zeff for PGA = 1 will double from
3.2MΩ to 6.4MΩ.
Modulator Input Circuitry
The SGM5860x modulator measures the input signal by
using internal capacitors that are continuously sampled and
reverse sampled between the differential inputs.
Table 9. Effective Impedances with Buffer On
When the chip is converting, it draws current from input. The
equal input impedance Zeff = VIN/IAVERAGE. Figure 6 shows the
input equal circuitry by their effective impedances.

Settling Time Using One-Shot Mode
Issue a STANDBY command can let chip go into low power
standby mode. A WAKEUP command can wake up the chip
and perform one time one-shot conversion. It will take t18 plus
3 nRDRY conversion cycles to wake up and fully settle the
conversion data. After the conversion, if we want to go to
standby again, another STANDBY command is needed.
Figure 13 shows the sequence.
Data Format
The SGM5860x output 24-bit data in binary two's complement
format. The ideal output codes for different input signals are
summarized as shown in Table 15.

General-Purpose Digital I/O (D0 to D3)
The SGM58601 has 4 digital I/O pins and the SGM58600/2
have 2 digital I/O pins. All I/O pins are separately controllable
by IO registers. During standby and power-down modes, the
GPIOs are still active. If GPIOs work as output, they keep
driving output. If the digital I/O pins are not used, either
configure them as input and connect them to ground or
configure them as outputs. This will reduce power dissipation.

The chip clock source can be an external oscillator (need an

ground.

Reset
There are two methods to reset the SGM5860x: the nRESET
input pin and RESET command.
To perform a system gain calibration, the user must supply a
full-scale input signal to the SGM5860x. The time required for

DETAILED DESCRIPTION (continued)
Synchronization
Power-Down Mode
There are two kinds of ways to synchronize input sampling,
SYNC command and nSYNC/nPDWN pin control. The first
method is to shift in 8-bit SYNC command, this makes the
chip ready to synchronize, and then issue WAKEUP
command to synchronize the sampling of the input signal on
the first rising edge of SCLK shifted in by WAKEUP. The
second method is to pull nSYNC/nPDWN pin low and then
set it high, synchronization happens on the rising edge of
nSYNC/nPDWN.
In power-down mode, all circuits are turned off, including
oscillator and clock output. To enter power-down, set
nSYNC/nPDWN pin low and keep it for 20 nDRDY cycles.
To get out of power-down mode, set the nSYNC/nPDWN pin
high, it will take the chip about 30ms to wake up if an external
crystal oscillator is used. It will take about 8192 CLKIN cycles
to wake up if an external clock source is used.
Power-Up
After a power-up, all registers is reset to their default values.
And then a self-calibration is performed automatically. We still
suggest that one more self-calibration by user's own control
software before the system starts running.
Standby Mode
In standby mode, the chip turns off all analog circuits and
some of the digital circuits. The oscillator circuits still keep
working. A WAKEUP command lets the chip exit standby
mode. Details see Figure 13.

address for read/write commands.
2. Issue this command after nDRDY goes low.
SELFCAL: Offset and Gain Self-Calibration
Issue an offset and gain self-calibration command. When the
calibration starts, nDRDY goes high. When the calibration
completes, nDRDY goes low, and settled data is ready. Do
not perform any more operation during this calibration.
SYSOCAL: System Offset Calibration
Issue a system offset calibration command. When beginning
the calibration, nDRDY goes high. When the calibration
completes, nDRDY goes low, and settled data is ready. Do
not do any more operation during this calibration.
