ADS41B49IRGZR

Texas Instruments · Analog To Digital Converters (ADC) · VQFN-48-EP(7x7)

ADS41B49IRGZR from Texas Instruments, in a VQFN-48-EP(7x7). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DRGND power_in Digital and output buffer ground.
2 DRVDD power_in 1.8-V digital and output buffer supply; absolute maximum range is -0.3 V to 2.1 V.
3 OVR_SDOUT output Out-of-range indicator after reset (READOUT = 0) and serial register readout pin when READOUT = 1; a 1.8-V CMOS output running off DRVDD.
4 CLKOUTM output Differential output clock, complement.
5 CLKOUTP output Differential output clock, true.
6 DFS input Data format select input that sets the data format (two's complement or offset binary) and the LVDS or CMOS output interface type.
7 OE input Output buffer enable input, active high; has an internal 100-kΩ pull-up resistor to DRVDD.
8 AVDD power_in 1.8-V analog power supply; absolute maximum range is -0.3 V to 2.1 V.
9 AGND power_in Analog ground.
10 CLKP input Differential clock input, positive.
11 CLKM input Differential clock input, negative.
12 AGND power_in Analog ground.
13 VCM output Outputs the common-mode voltage that can be used externally to bias the analog input pins.
14 AGND power_in Analog ground.
15 INP input Differential analog input, positive; absolute input voltage range is -0.3 V to the minimum of 1.9 V or AVDD + 0.3 V.
16 INM input Differential analog input, negative; absolute input voltage range is -0.3 V to the minimum of 1.9 V or AVDD + 0.3 V.
17 AGND power_in Analog ground.
18 AVDD power_in 1.8-V analog power supply; absolute maximum range is -0.3 V to 2.1 V.
19 AGND power_in Analog ground.
20 AVDD power_in 1.8-V analog power supply; absolute maximum range is -0.3 V to 2.1 V.
21 AVDD_BUF power_in 3.3-V input buffer supply; absolute maximum range is -0.3 V to 3.9 V.
22 AVDD power_in 1.8-V analog power supply; absolute maximum range is -0.3 V to 2.1 V.
23 RESERVED input Digital control pin reserved for future use.
24 AVDD power_in 1.8-V analog power supply; absolute maximum range is -0.3 V to 2.1 V.
25 AGND power_in Analog ground.
26 AVDD power_in 1.8-V analog power supply; absolute maximum range is -0.3 V to 2.1 V.
27 SEN input Serial interface enable input when RESET is low; when RESET is high it has no function and must be tied to AVDD (internal 180-kΩ pull-up to AVDD).
28 SDATA input Serial interface data input when RESET is low; when RESET is high it functions as the STANDBY control pin (internal 180-kΩ pull-down).
29 SCLK input Serial interface clock input when RESET is low; when RESET is high it must be tied to ground (internal 180-kΩ pull-down).
30 RESET input Serial interface reset input; a high pulse wider than 10 ns initializes the registers, and it has an internal 100-kΩ pull-down resistor.
31 NC unconnected Do not connect.
32 NC unconnected Do not connect.
33 D0_D1_M output Differential output data D0 and D1 multiplexed, complement.
34 D0_D1_P output Differential output data D0 and D1 multiplexed, true.
35 DRVDD power_in 1.8-V digital and output buffer supply; absolute maximum range is -0.3 V to 2.1 V.
36 DRGND power_in Digital and output buffer ground.
37 D2_D3_M output Differential output data D2 and D3 multiplexed, complement.
38 D2_D3_P output Differential output data D2 and D3 multiplexed, true.
39 D4_D5_M output Differential output data D4 and D5 multiplexed, complement.

43 D8_D9_M output Differential output data D8 and D9 multiplexed, complement.
44 D8_D9_P output Differential output data D8 and D9 multiplexed, true.
45 D10_D11_M output Differential output data D10 and D11 multiplexed, complement.
46 D10_D11_P output Differential output data D10 and D11 multiplexed, true.
47 D12_D13_M output Differential output data D12 and D13 multiplexed, complement.
48 D12_D13_P output Differential output data D12 and D13 multiplexed, true.
49 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
