ACPL-785E-300 is an optically isolated amplifier (Optically Isolated Amplifiers) from Broadcom Limited. It belongs to the ACPL-5 series of products.
ACPL-785E-300 amplifier core information:
The minimum operating temperature of ACPL-785E-300 is - 55 C and the maximum operating temperature is + 125 C. The corresponding working power supply current is 10.7 mA
The amplifier gain of ACPL-785E-300 can reach: 8 V/V (Amplifier gain is the logarithm of the ratio of amplifier output power to input power, used to indicate the degree of power amplification. It also refers to the amplification factor of voltage or current. Similarly, decibels is the unit of amplifier gain).
When a voltage difference of 0.6 mV is applied between the input pins of the ACPL-785E-300, the output voltage of this amplifier is 0V. (That is, its input bias voltage is 0.6 mV)

The HCPL-7850, HCPL-7851, and ACPL-785E are isolation
amplifiers that provide accurate, electrically isolated and
amplified representations of voltage and current. When used
with a shunt resistor to monitor the motor phase current in a
high-speed motor drive, the device offers superior reliability
compared with the traditional solutions such as current
transformers and Hall-effect sensors. These devices consist of a
sigma-delta analog-to-digital converter optically coupled to a
digital-to-analog converter in a hermetically sealed package.
The products are capable of operation and storage over the full
military temperature range and can be purchased as a
commercial product (HCPL-7850), with full MIL-PRF-38534
Class H testing (HCPL-7851), with MIL-PRF-38534 Class E testing
(ACPL-785E) (Class K with exceptions) or from the DLA Standard

Superior performance in design-critical specifications, such as
common-mode rejection, offset voltage, nonlinearity, and
operating temperature, makes the HCPL-7850, HCPL-7851 and
ACPL-785E excellent choices for designing reliable products
such as motor controllers and inverters.
With common-mode rejection of 8 kV/μs, these devices are
suitable for noisy electrical environments such as those
generated by the high switching rates of power IGBTs.
Low offset voltage together with a low offset voltage
temperature coefficient permits accurate use of
auto-calibration techniques.
Gain tolerance of 5% with 0.1% nonlinearity further provide
the performance necessary for accurate feedback and control.

Commercial parts receive 100% testing at 25°C (Subgroups 1 and 9). SMD, Class H and Class E receive 100% testing at 25, 125, and –55°C (Subgroups 1 and 9,

Exact offset value is dependent on layout of external bypass capacitors. The offset value in the data sheet corresponds to Broadcom’s recommended layout
(see
Figure 26
and
Figure 27).
Nonlinearity is defined as half of the peak-to-peak output deviation from the best-fit gain line, expressed as a percentage of the full-scale differential output
voltage.
Device considered a two-terminal device: Pins 1, 2, 3, and 4 are shorted together, and pins 5, 6, 7, and 8 are shorted together.
Because of the switched capacitor nature of the sigma-delta A/D converter, time averaged values are shown.
CMRR
IN
is defined as the ratio of the gain for differential inputs applied between pins 2 and 3 to the gain for both common-mode inputs applied to both pins
2 and 3 with respect to pin 4.
When the differential input signal exceeds approximately 320 mV, the outputs will limit at the typical values shown.
Short-circuit current is the amount of output current generated when either output is shorted to V
