OPAMPEMLIB

Detailed Description

Operational Amplifier (OPAMP) peripheral API.

This module contains functions to:

All OPAMP functions assume that the VDAC clock is running. If VDAC is not used, the clock can be turned off when the OPAMPs are configured.

If the available gain values don't suit the application at hand, the resistor ladders can be disabled and external gain programming resistors used.

A number of predefined OPAMP setup macros are available for configuration of the most common OPAMP topologies (see figures below).

Note
The terms POSPAD and NEGPAD in the figures are used to indicate that these pads should be connected to a suitable signal ground.


Unity gain voltage follower.
Use predefined macro OPA_INIT_UNITY_GAIN.

opaPrsModeDefault 

Default value when PRS is not the trigger.

opaPrsModePulsed 

PRS trigger is a pulse that starts the OPAMP warmup sequence. The end of the warmup sequence is controlled by timeout settings in OPAxTIMER.

opaPrsModeTimed 

PRS trigger is a pulse long enough to provide the OPAMP warmup sequence. The end of the warmup sequence is controlled by the edge of the pulse.

Function Documentation

void OPAMP_Disable ( VDAC_TypeDef *  dac,
OPAMP_TypeDef  opa 
)

Disable an Operational Amplifier.

Parameters
[in]dacA pointer to the VDAC peripheral register block.
[in]opaSelects an OPA, valid values are OPA0, OPA1, and OPA2.

void OPAMP_Enable ( VDAC_TypeDef *  dac,
OPAMP_TypeDef  opa,
const OPAMP_Init_TypeDef init 
)

Configure and enable an Operational Amplifier.

Note
The value of the alternate output enable bit mask in the OPAMP_Init_TypeDef structure should consist of one or more of the VDAC_OPA_OUT_ALTOUTPADEN_OUT[output#] flags (defined in <part_name>_vdac.h) OR'ed together.

  • VDAC_OPA_OUT_ALTOUTPADEN_OUT0
  • VDAC_OPA_OUT_ALTOUTPADEN_OUT1
  • VDAC_OPA_OUT_ALTOUTPADEN_OUT2
  • VDAC_OPA_OUT_ALTOUTPADEN_OUT3
  • VDAC_OPA_OUT_ALTOUTPADEN_OUT4
For example:
init.outPen = VDAC_OPA_OUT_ALTOUTPADEN_OUT0 | VDAC_OPA_OUT_ALTOUTPADEN_OUT4;
Parameters
[in]dacA pointer to the VDAC peripheral register block.
[in]opaSelects an OPA, valid values are OPA0, OPA1, and OPA2.
[in]initA pointer to a structure containing OPAMP initialization information.
