LM94022, LM94022-Q1

SNIS140F –MAY 2006–REVISED SEPTEMBER 2015

LM94022/-Q1 1.5-V, SC70, Multi-Gain Analog Temperature Sensor With Class-AB Output

1 Features

3 Description

The LM94022/-Q1 device is a precision analog output

CMOS integrated-circuit temperature sensor with

selectable linear negative temperature coefficient

•

LM94022/-Q1 is AEC-Q100 Grade 0 qualified and

is Manufactured on an Automotive Grade Flow

Low 1.5-V to 5.5-V Operation With Low 5.4-µA

Supply Current

(NTC).

A class-AB output structure gives the

LM94022/-Q1 strong output source and sink current

capability for driving heavy transient loads such as

that presented by the input of a sample-and-hold

analog-to-digital converter. The low 5.4-µA supply

current and 1.5-V operating voltage of the LM94022/-

Q1 make it ideal for battery-powered systems as well

as general temperature-sensing applications.

Push-Pull Output With ±50-µA Source Current

Capability

•

Four Selectable Gains

Very Accurate Over Wide Temperature Range of

−50°C to +150°C:

–

±1.5ºC Temperature Accuracy for 20ºC to

40ºC Range

The Gain Select 1 (GS1) and Gain Select 0 (GS0)

logic inputs select one of four gains for the

temperature-to-voltage output transfer function: −5.5

mV/°C, −8.2 mV/°C, −10.9 mV/°C, and −13.6 mV/°C.

Selecting –5.5 mV/°C (GS1 and GS0 both tied low),

allows the LM94022/-Q1 to operate down to 1.5-V

supply while measuring temperature over the full

range of −50°C to +150°C. Maximum temperature

sensitivity, –13.6 mV/°C, is selected when GS1 and

GS0 are both tied high. The gain-select inputs can be

tied directly to V_DDor Ground without any pullup or

pulldown resistors, reducing component count and

board area. These inputs can also be driven by logic

signals allowing the system to optimize the gain

during operation or system diagnostics.

±1.8ºC Temperature Accuracy for –50ºC to

70ºC Range

±2.1ºC Temperature Accuracy for –50ºC to

90ºC Range

±2.7ºC Temperature Accuracy for –50ºC to

150ºC Range
