BANG-BANG Controller

FEATURES

DESCRIPTIO

The LTC^®1041 is a monolithic CMOS BANG-BANG

controller manufactured using Linear Technology’s

enhanced LTCMOS™ silicon gate process. BANG-BANG

loops are characterized by turning the control element

fully ON or fully OFF to regulate the average value of

the parameter to be controlled. The SET POINT input

determines the average control value and the DELTA input

sets the deadband. The deadband is always 2 x DELTA and

is centered around the SET POINT. Independent control

of the SET POINT and deadband, with no interaction, is

made possible by the unique sampling input structure of

the LTC1041.

■

Micropower 1.5µW (1 Sample/Second)

■

Wide Supply Range 2.8V to 16V

■

High Accuracy

Guaranteed SET POINT Error ±0.5mV Max

Guaranteed Deadband ±0.1% of Value Max

Wide Input Voltage Range V⁺to Ground

■

TTL Outputs with 5V Supply

■

Two Independent Ground-Referred Control Inputs

■

Small Size 8-Pin SO

APPLICATIO S

AnexternalRCconnectedtotheOSCpinsetsthesampling

rate. At the start of each sample, internal power to the

analog section is switched on for ≈ 80µs. During this time,

the analog inputs are sampled and compared. After the

comparison is complete, power is switched off. This

achieves extremely low average power consumption

at low sampling rates. CMOS logic holds the output

continuously while consuming virtually no power.

Tokeepsystempoweratanabsoluteminimum,aswitched

power output (V_P-P) is provided. External loads, such as

bridge networks and resistive dividers, can be driven by

this switched output.

The output logic sense (i.e., ON = V⁺) can be reversed

(i.e., ON = GND) by interchanging the V_INand SET POINT

inputs. This has no other effect on the operation of

the LTC1041.
