Programmable op amp offers power/performance flexibility
1 min read
Diodes has introduced its own variant of the TLC271 programmable op amp.
The new module offers a bias select mode, enabling closer matching of power dissipation and AC performance with the specific requirements of battery powered consumer and industrial products.
To help extend battery cell life, its low bias mode helps reduce power dissipation, while medium and high bias modes progressively increase op amp AC performance.
Bias modes can also be changed, allowing the device to be idle in power saving mode then switch to a defined high performance mode in response to application demand.
A companion part to the TLC271 has also been launched. The TLC271L is a fixed metal mask option that has the bias select pin removed and operates continuously in power saving, low bias mode.
By reducing supply currents down to 10µA and operating at a 3V supply voltage, the TLC271 is suitable for a range of Li+ battery and MCU supplies. The op amp provides an optimised output range for low voltage applications by featuring a full rail to rail output swing of up to 16V.
The TLC271's high input impedance and low bias currents, combined with dependable, common mode and supply voltage rejection, make it a good choice for high performance circuit designs.
It is available in both commercial temperature (0 to +70ºC) and industrial temperature (-40 to 125ºC) grades.
