# LMV242LD

**Texas Instruments** · RF Front End Circuits · DFN-10-EP(3x3)

LMV242LD from Texas Instruments, in a DFN-10-EP(3x3). 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 | OUT1 | output | Output pin connected to PA of channel 1 for RF control voltage. |
| 2 | OUT2 | output | Output pin connected to PA of channel 2 for RF control voltage. |
| 3 | COMP2 | passive | Frequency compensation pin; BS signal switches between OUT1 and OUT2 compensation networks. |
| 4 | VDD | power_in | Positive supply voltage, 2.6V to 5.5V range. |
| 5 | RFIN | input | RF input connected to coupler output for detecting PA and antenna RF power level, input range −50 to 0 dBm. |
| 6 | VRAMP | input | Analog input for setting RF output power level; useful input range 0.2V to 1.8V although 0V to VDD tolerated. |
| 7 | TX_EN | input | Schmitt trigger logic input for transmit enable; low <0.8V shuts down chip, high >1.8V enables chip. |
| 8 | BS | input | Schmitt trigger band select digital input; high selects OUT1, low selects OUT2. |
| 9 | COMP1 | passive | Compensation pin for connecting external RC network between COMP1 and COMP2 for loop compensation and closed-loop frequency response control. |
| 10 | GND | power_in | Power ground reference. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
