ADS7841EB

Texas Instruments · Analog To Digital Converters (ADCs) · SSOP-16-150mil

ADS7841EB from Texas Instruments, in a SSOP-16-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 +VCC power_in Power supply input, 2.7 V to 5 V. Must be tied together with pin 9. Bypass with a low-ESR ceramic capacitor to GND.
2 CH0 input Analog input channel 0. Full-scale span 0 to VREF; absolute range -0.2 V to VCC+0.2 V.
3 CH1 input Analog input channel 1. Full-scale span 0 to VREF; absolute range -0.2 V to VCC+0.2 V.
4 CH2 input Analog input channel 2. Full-scale span 0 to VREF; absolute range -0.2 V to VCC+0.2 V.
5 CH3 input Analog input channel 3. Full-scale span 0 to VREF; absolute range -0.2 V to VCC+0.2 V.
6 COM input Ground reference for the analog inputs. Sets the zero-code voltage in single-ended mode; tie to ground or the local analog ground reference point.
7 /SHDN input Shutdown, active LOW. Driving this pin LOW places the device into a very low-power shutdown mode (<15 uW). Tie HIGH for normal operation.
8 VREF input External voltage reference input, 100 mV to VCC. Sets the full-scale conversion range. Bypass with a low-ESR ceramic capacitor to GND.
9 +VCC power_in Power supply input, 2.7 V to 5 V. Must be tied together with pin 1. Bypass with a low-ESR ceramic capacitor to GND.
10 GND power_in Device ground return.
11 MODE input Conversion mode select. When LOW, the device always performs a 12-bit conversion; when HIGH, resolution is set by the MODE bit in the control byte.
12 DOUT tri_state Serial data output. Data is shifted out on the falling edge of DCLK; high-impedance when /CS is HIGH.
13 BUSY tri_state Busy output. Indicates when a conversion is in progress; high-impedance when /CS is HIGH.
14 DIN input Serial data input. When /CS is LOW, DIN is latched on the rising edge of DCLK.
15 /CS input Chip select, active LOW. Controls conversion timing and enables the serial input/output register.
16 DCLK input External serial clock input, up to 3.2 MHz. Runs the SAR conversion process and synchronizes serial I/O.
