THS6222IRHFR

Texas Instruments · Differential Amplifiers · VQFN-24-EP(4x5)

THS6222IRHFR from Texas Instruments, in a VQFN-24-EP(4x5). 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 D1_IN+ input Amplifier D1 noninverting input; common-mode input voltage ±3.0V with respect to midsupply at VS = 12V
2 D2_IN+ input Amplifier D2 noninverting input; common-mode input voltage ±3.0V with respect to midsupply at VS = 12V
3 DGND power_in Ground reference for bias control pins; voltage must range from VS- to (VS+) - 5V per specification
4 IADJ input Bias current adjustment pin; external resistor to ground adjusts quiescent current across full-bias to shutdown modes
5 VCM output Common-mode buffer output providing integrated 1/2 Vs voltage reference; typical offset ±2.5mV for AC-coupled input applications
6 NC unconnected No internal connection
7 NC unconnected No internal connection
8 NC unconnected No internal connection
9 NC unconnected No internal connection
10 NC unconnected No internal connection
11 NC unconnected No internal connection
12 NC unconnected No internal connection
13 NC unconnected No internal connection
14 NC unconnected No internal connection
15 NC unconnected No internal connection
16 NC unconnected No internal connection
17 D2_OUT output Amplifier D2 output; differential transmission line driver pair with D1_OUT, supplies ±338mA into 25Ω load at VS = 12V
18 D2_IN- input Amplifier D2 inverting input; part of D2 differential input pair referenced to DGND
19 D1_IN- input Amplifier D1 inverting input; part of D1 differential input pair referenced to DGND
20 D1_OUT output Amplifier D1 output; differential transmission line driver pair with D2_OUT, supplies ±338mA into 25Ω load at VS = 12V
21 VS+ power_in Positive power-supply connection; operating range 8V to 32V for single-supply or split-supply operation
22 VS- power_in Negative power-supply connection; ground return for single-supply or negative rail for split-supply (−3V to −27V from reference)
23 BIAS-1 input Bias mode control LSB; logic level relative to DGND (0.8V for logic 0, 2.1V for logic 1) selects operating mode; floating input causes shutdown
24 BIAS-2 input Bias mode control MSB; logic level relative to DGND (0.8V for logic 0, 2.1V for logic 1) selects operating mode; floating input causes shutdown
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
